The Red Dog Saloon is a drinking establishment at 278 South Franklin Street in Juneau , Alaska , U.S. The Red Dog has been recognized by the Alaska Legislature for its longevity as the oldest man-made tourist attraction in Juneau.
112-543: Founded during Juneau's mining era, the Saloon has been in operation for decades. For a time, "Ragtime Hattie" played the piano in white gloves and a silver dollar halter top . Later, in territorial days, the owners would often meet the tour boats at the docks with a mule that wore a sign saying, "follow my ass to the Red Dog Saloon." The saloon hosted an episode of The Ed Sullivan Show just after Alaska became
224-561: A grand piano , the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings and uses gravity as its means of return to a state of rest. Grand pianos range in length from approximately 1.5–3 m (4 ft 11 in – 9 ft 10 in). Some of the lengths have been given more-or-less customary names, which vary from time to time and place to place, but might include: All else being equal, longer pianos with longer strings have larger, richer sound and lower inharmonicity of
336-587: A loudspeaker . The electric pianos that became most popular in pop and rock music in the 1960s and 1970s, such as the Fender Rhodes use metal tines in place of strings and use electromagnetic pickups similar to those on an electric guitar . The resulting electrical, analogue signal can then be amplified with a keyboard amplifier or electronically manipulated with effects units . In classical music, electric pianos are mainly used as inexpensive rehearsal or practice instruments. Electric pianos, particularly
448-410: A pedal keyboard at the base, designed to be played by the feet. The pedals may play the existing bass strings on the piano, or rarely, the pedals may have their own set of bass strings and hammer mechanisms. While the typical intended use for pedal pianos is to enable a keyboardist to practice pipe organ music at home, a few players of pedal piano use it as a performance instrument. Wadia Sabra had
560-496: A pitch by this method. According to the American National Standards Institute , pitch is the auditory attribute of sound allowing those sounds to be ordered on a scale from low to high. Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude , of

They quickly gained a reputation for the splendour and powerful tone of their instruments, with Broadwood constructing pianos that were progressively larger, louder, and more robustly constructed. They sent pianos to both Joseph Haydn and Ludwig van Beethoven , and were

Digital pianos are also non-acoustic and do not have strings or hammers. They use digital audio sampling technology to reproduce the acoustic sound of each piano note accurately. They also must be connected to a power amplifier and speaker to produce sound (however, most digital pianos have

Digital pianos can include sustain pedals, weighted or semi-weighted keys, multiple voice options (e.g., sampled or synthesized imitations of electric piano, Hammond organ , violin , etc.), and MIDI interfaces. MIDI inputs and outputs connect a digital piano to other electronic instruments or musical devices. For example,

Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents ). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if
1120-483: A digital piano's MIDI out signal could be connected by a patch cord to a synth module , which would allow the performer to use the keyboard of the digital piano to play modern synthesizer sounds. Early digital pianos tended to lack a full set of pedals, but the synthesis software of later models such as the Yamaha Clavinova series synthesised the sympathetic vibration of the other strings (such as when
1232-476: A familiar instrument in the Western world. The piano was based on earlier technological innovations in keyboard instruments . Pipe organs had been used since antiquity, and as such the development of pipe organs enabled instrument builders to learn about creating keyboard mechanisms for sounding pitches . The first string instruments with struck strings were the hammered dulcimers , which were introduced in

The piano is widely employed in classical , jazz , traditional and popular music for solo and ensemble performances, accompaniment, and for composing , songwriting and rehearsals. Despite its weight and cost, the piano's versatility, the extensive training of musicians, and its availability in venues, schools, and rehearsal spaces have made it
1456-636: A few decades of use. Beginning in 1961, the New York branch of the Steinway firm incorporated Teflon , a synthetic material developed by DuPont , for some parts of its Permafree grand action in place of cloth bushings, but abandoned the experiment in 1982 due to excessive friction and a "clicking" that developed over time; Teflon is "humidity stable" whereas the wood adjacent to the Teflon swells and shrinks with humidity changes, causing problems. More recently,
1568-627: A form of piano wire made from cast steel ; it was "so superior to the iron wire that the English firm soon had a monopoly." A better steel wire was developed in 1840 by the Viennese firm Martin Miller, and a period of innovation and intense competition ensued, with rival brands of piano wire being tested against one another at international competitions, leading ultimately to the modern form of piano wire. Several important advances included changes to
1680-525: A harmonic produced from three octaves below. This lets close and widespread octaves sound pure, and produces virtually beatless perfect fifths . This gives the concert grand a brilliant, singing and sustaining tone quality—one of the principal reasons that full-size grands are used in the concert hall. Smaller grands satisfy the space and cost needs of domestic use; as well, they are used in some small teaching studios and smaller performance venues. Upright pianos, also called vertical pianos, are more compact with
1792-478: A lower octave's corresponding sharp overtone rather than to a theoretically correct octave. If octaves are not stretched, single octaves sound in tune, but double—and notably triple—octaves are unacceptably narrow. Stretching a small piano's octaves to match its inherent inharmonicity level creates an imbalance among all the instrument's intervallic relationships. In a concert grand, however, the octave "stretch" retains harmonic balance, even when aligning treble notes to
1904-613: A massive, strong, cast iron frame. Also called the "plate", the iron frame sits atop the soundboard , and serves as the primary bulwark against the force of string tension that can exceed 20 tons (180 kilonewtons) in total for a modern grand piano. The single piece cast iron frame for square piano was patented in 1825 in Boston by Alpheus Babcock , combining the metal hitch pin plate (1821, claimed by Broadwood on behalf of Samuel Hervé) and resisting bars (Thom and Allen, 1820, but also claimed by Broadwood and Érard). Babcock later worked for

With technological advances , amplified electric pianos (1929), electronic pianos (1970s), and digital pianos (1980s) have been developed. The first electric pianos from the late 1920s used metal strings with a magnetic pickup , an amplifier and

When the invention became public, as revised by Henri Herz , the double escapement action gradually became standard in grand pianos and is still incorporated into all grand pianos currently produced in the 2000s. Other improvements of the mechanism included the use of firm felt hammer coverings instead of layered leather or cotton. Felt, which Jean-Henri Pape

In standard Western equal temperament , the notion of pitch is insensitive to "spelling": the description "G 4 double sharp" refers to the same pitch as A 4 ; in other temperaments, these may be distinct pitches. Human perception of musical intervals
2352-441: A piano are made of a steel core wrapped with one or two layers of copper wire, to increase their mass whilst retaining flexibility. If all strings throughout the piano's compass were individual (monochord), the massive bass strings would overpower the upper ranges. Makers compensate for this with the use of double (bichord) strings in the tenor and triple (trichord) strings throughout the treble. The plate (harp), or metal frame, of

This is especially true of the outer rim, which is most commonly made of hardwood , typically hard maple or beech , and its massiveness serves as an essentially immobile object from which the flexible soundboard can best vibrate. According to Harold A. Conklin, the purpose of a sturdy rim is so that, "... the vibrational energy will stay as much as possible in

Some electronic feature-equipped pianos such as the Yamaha Disklavier electronic player piano, introduced in 1987, are outfitted with electronic sensors for recording and electromechanical solenoids for player piano-style playback. Sensors record the movements of
2688-419: A piano is usually made of cast iron. A massive plate is advantageous. Since the strings vibrate from the plate at both ends, an insufficiently massive plate would absorb too much of the vibrational energy that should go through the bridge to the soundboard. While some manufacturers use cast steel in their plates, most prefer cast iron. Cast iron is easy to cast and machine, has flexibility sufficient for piano use,
2800-471: A piano. An inventory made by his employers, the Medici family, indicates the existence of a piano by 1700. The three Cristofori pianos that survive today date from the 1720s. Cristofori named the instrument un cimbalo di cipresso di piano e forte ("a keyboard of cypress with soft and loud"), abbreviated over time as pianoforte , fortepiano , and later reduced to only piano . Cristofori's great success

Cristofori's piano action was a model for the many approaches to piano actions that followed in the next century. Cristofori's early instruments were made with thin strings and were much quieter than the modern piano, though they were louder and had more sustain compared to

Modern pianos have two basic configurations, the grand piano and the upright piano, with various styles of each. There are also specialized and novelty pianos, electric pianos based on electromechanical designs, electronic pianos that synthesize piano-like tones using oscillators, and digital pianos using digital samples of acoustic piano sounds.

The oscillations of sound waves can often be characterized in terms of frequency . Pitches are usually associated with, and thus quantified as, frequencies (in cycles per second, or hertz), by comparing the sounds being assessed against sounds with pure tones (ones with periodic , sinusoidal waveforms). Complex and aperiodic sound waves can often be assigned

The precise way this temporal structure helps code for pitch at higher levels is still debated, but the processing seems to be based on an autocorrelation of action potentials in the auditory nerve. However, it has long been noted that a neural mechanism that may accomplish a delay—a necessary operation of a true autocorrelation—has not been found. At least one model shows that a temporal delay

3584-660: A vertical structure of the frame and strings. The mechanical action structure of the upright piano was invented in London in 1826 by Robert Wornum, and upright models became the most popular model for domestic use. Upright pianos take up less space than a grand piano and as such are a better size for use in private homes for domestic music-making and practice. The hammers move horizontally and return to their resting position via springs, which are susceptible to degradation. Upright pianos with unusually tall frames and long strings were sometimes marketed as upright grand pianos, but that label
3696-463: Is a keyboard instrument that produces sound when its keys are depressed, activating an action mechanism where hammers strike strings . Modern pianos have a row of 88 black and white keys, tuned to a chromatic scale in equal temperament . A musician who specializes in piano is called a pianist . There are two main types of piano: the grand piano and the upright piano . The grand piano offers better sound and more precise key control, making it
3808-472: Is a major auditory attribute of musical tones , along with duration , loudness , and timbre . Pitch may be quantified as a frequency , but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in
3920-465: Is approximately logarithmic with respect to fundamental frequency : the perceived interval between the pitches "A220" and "A440" is the same as the perceived interval between the pitches A440 and A880 . Motivated by this logarithmic perception, music theorists sometimes represent pitches using a numerical scale based on the logarithm of fundamental frequency. For example, one can adopt the widely used MIDI standard to map fundamental frequency, f , to
4032-483: Is flexible enough to include "microtones" not found on standard piano keyboards. For example, the pitch halfway between C (60) and C ♯ (61) can be labeled 60.5. The following table shows frequencies in Hertz for notes in various octaves, named according to the "German method" of octave nomenclature : The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems . In
4144-465: Is misleading. Some authors classify modern pianos according to their height and to modifications of the action that are necessary to accommodate the height. Upright pianos are generally less expensive than grand pianos. Upright pianos are widely used in churches, community centers, schools, music conservatories and university music programs as rehearsal and practice instruments, and they are popular models for in-home purchase. The toy piano , introduced in
4256-580: Is much more resistant to deformation than steel, and is especially tolerant of compression. Plate casting is an art, since dimensions are crucial and the iron shrinks about one percent during cooling. Including an extremely large piece of metal in a piano is potentially an aesthetic handicap. Piano makers overcome this by polishing, painting, and decorating the plate. Plates often include the manufacturer's ornamental medallion. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during
4368-537: Is one where a listener can possibly (or relatively easily) discern the pitch. Sounds with definite pitch have harmonic frequency spectra or close to harmonic spectra. A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once. The vibration with the lowest frequency is called the fundamental frequency ; the other frequencies are overtones . Harmonics are an important class of overtones with frequencies that are integer multiples of
4480-494: Is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another. For instance, a snare drum sounds higher pitched than a bass drum though both have indefinite pitch, because its sound contains higher frequencies. In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but sounds of indefinite pitch do not neatly correspond to any specific pitch. A pitch standard (also concert pitch )
4592-475: Is the conventional pitch reference that musical instruments in a group are tuned to for a performance. Concert pitch may vary from ensemble to ensemble, and has varied widely over musical history. Standard pitch is a more widely accepted convention. The A above middle C is usually set at 440 Hz (often written as "A = 440 Hz " or sometimes "A440"), although other frequencies, such as 442 Hz, are also often used as variants. Another standard pitch,

4816-477: Is unnecessary to produce an autocorrelation model of pitch perception, appealing to phase shifts between cochlear filters; however, earlier work has shown that certain sounds with a prominent peak in their autocorrelation function do not elicit a corresponding pitch percept, and that certain sounds without a peak in their autocorrelation function nevertheless elicit a pitch. To be a more complete model, autocorrelation must therefore apply to signals that represent
4928-594: The Chickering & Mackays firm who patented the first full iron frame for grand pianos in 1843. Composite forged metal frames were preferred by many European makers until the American system was fully adopted by the early 20th century. The increased structural integrity of the iron frame allowed the use of thicker, tenser, and more numerous strings. In 1834, the Webster & Horsfal firm of Birmingham brought out

Thus far these parts have performed reasonably, but it will take decades to know if they equal the longevity of wood. In all but the lowest quality pianos,
5152-588: The Middle Ages in Europe. During the Middle Ages, there were several attempts at creating stringed keyboard instruments with struck strings. By the 17th century, the mechanisms of keyboard instruments such as the clavichord and the harpsichord were well developed. In a clavichord the strings are struck by tangents, while in a harpsichord they are mechanically plucked by quills when the performer depresses
5264-791: The Steinway concert grand (Model D) weighs 480 kg (1,060 lb). The largest piano available on the general market, the Fazioli F308, weighs 570 kg (1,260 lb). The pinblock, which holds the tuning pins in place, is another area where toughness is important. It is made of hardwood (typically hard maple or beech) and is laminated for strength, stability and longevity. Piano strings (also called piano wire ), which must endure years of extreme tension and hard blows, are made of high carbon steel. They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. The bass strings of
5376-464: The acoustic energy to the air. When the key is released, a damper stops the string's vibration, ending the sound. Most notes have three strings, except for the bass, which graduates from one to two. Notes can be sustained when the keys are released by the use of pedals at the base of the instrument, which lift the dampers off the strings. The sustain pedal allows pianists to connect and overlay sound, and achieve expressive and colorful sonority. In
5488-538: The octave doubles the frequency of a note; for example, an octave above A440 is 880 Hz. If however the first overtone is sharp due to inharmonicity , as in the extremes of the piano, tuners resort to octave stretching . In atonal , twelve tone , or musical set theory , a "pitch" is a specific frequency while a pitch class is all the octaves of a frequency. In many analytic discussions of atonal and post-tonal music, pitches are named with integers because of octave and enharmonic equivalency (for example, in
5600-549: The transposing piano in 1801. This rare instrument has a lever under the keyboard to move the keyboard relative to the strings, so a pianist can play in a familiar key while the music sounds in a different key.

Some early pianos had shapes and designs that are no longer in use. The square piano (not truly square, but rectangular) was cross strung at an extremely acute angle above the hammers, with
5936-522: The 1820s, the center of piano innovation had shifted to Paris, where the Pleyel firm manufactured pianos used by Frédéric Chopin , and the Érard firm manufactured those used by Franz Liszt . In 1821, Sébastien Érard invented the double escapement action, which incorporated a repetition lever (also called the balancier ) that permitted repeating a note even if the key had not return to its resting position. This facilitated rapid playing of repeated notes,

The numerous parts of a piano action are generally made from hardwood, such as maple, beech, or hornbeam ; however, since World War II, makers have also incorporated plastics. Early plastics used in some pianos in the late 1940s and 1950s, proved problematic when they lost strength after
6160-412: The 19th century, influenced by Romantic music trends, the fortepiano underwent changes such as the use of a cast iron frame (which allowed much greater string tensions) and aliquot stringing which gave grand pianos a more powerful sound, a longer sustain, and a richer tone. Later in the century, as the piano became more common it allowed families to listen to a newly published musical piece by having
6272-430: The 19th century, is a small piano-like instrument that generally uses round metal rods to produce sound, rather than strings. The US Library of Congress recognizes the toy piano as a unique instrument with the subject designation, Toy Piano Scores: M175 T69. In 1863, Henri Fourneaux invented the player piano , which plays itself from a piano roll . A machine perforates a performance recording into rolls of paper, and
6384-522: The A above middle C to 432 Hz or 435 Hz when performing repertoire from the Romantic era. Transposing instruments have their origin in the variety of pitch standards. In modern times, they conventionally have their parts transposed into different keys from voices and other instruments (and even from each other). As a result, musicians need a way to refer to a particular pitch in an unambiguous manner when talking to each other. For example,

Electronic pianos are non-acoustic; they do not have strings, tines or hammers, but are a type of analog synthesizer that simulates or imitates piano sounds using oscillators and filters that synthesize the sound of an acoustic piano. They must be connected to a keyboard amplifier and speaker to produce sound (however, some electronic keyboards have

When averaged, the remaining shifts followed the directions of Stevens's curves but were small (2% or less by frequency, i.e. not more than a semitone). Theories of pitch perception try to explain how the physical sound and specific physiology of the auditory system work together to yield the experience of pitch. In general, pitch perception theories can be divided into place coding and temporal coding . Place theory holds that

Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration ( audio frequency ). Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute which can be measured. Pitch is the subjective perception of

While the clavichord allows expressive control of volume and sustain, it is relatively quiet even at its loudest. The harpsichord produces a sufficiently loud sound, especially when a coupler joins each key to both manuals of a two-manual harpsichord, but it offers no dynamic or expressive control over individual notes. The piano in some sense offers

The short cottage upright or pianino with vertical stringing—made popular by Robert Wornum around 1815—was built into the 20th century. They are informally called birdcage pianos because of their prominent damper mechanism. The oblique upright, popularized in France by Roller & Blanchet during the late 1820s, was diagonally strung throughout its compass. The tiny spinet upright

Reproducing systems have ranged from relatively simple, playback-only models to professional models that can record performance data at resolutions that exceed the limits of normal MIDI data. The unit mounted under the keyboard of the piano can play MIDI or audio software on its CD. Pianos can have over 12,000 individual parts, supporting six functional features: keyboard, hammers, dampers, bridge, soundboard, and strings. Many parts of

The thick wooden posts on the underside (grands) or back (uprights) of the piano stabilize the rim structure and are made of softwood for stability. The requirement of structural strength, fulfilled by stout hardwood and thick metal, makes a piano heavy. Even a small upright can weigh 136 kg (300 lb), and
7504-456: The fundamental. Whether or not the higher frequencies are integer multiples, they are collectively called the partials , referring to the different parts that make up the total spectrum. A sound or note of indefinite pitch is one that a listener finds impossible or relatively difficult to identify as to pitch. Sounds with indefinite pitch do not have harmonic spectra or have altered harmonic spectra—a characteristic known as inharmonicity . It

Piano making flourished during the late 18th century in the Viennese school , which included Johann Andreas Stein (who worked in Augsburg , Germany) and the Viennese makers Nannette Streicher (daughter of Stein) and Anton Walter . Viennese-style pianos were built with wood frames, two strings per note, and leather-covered hammers. Some of these Viennese pianos had

This design is attributed to Christian Ernst Friderici (a pupil of Gottfried Silbermann) in Germany and Johannes Zumpe in England, and it was improved by changes first introduced by Guillaume-Lebrecht Petzold in France and Alpheus Babcock in the United States. Square pianos were built in great numbers through the 1840s in Europe and the 1890s in the United States, and saw

On playback, the solenoids move the keys and pedals and thus reproduce the original performance. Modern Disklaviers typically include an array of electronic features, such as a built-in tone generator for playing back MIDI accompaniment tracks, speakers, MIDI connectivity that supports communication with computing devices and external MIDI instruments, additional ports for audio and SMPTE input/output (I/O), and Internet connectivity. Disklaviers have been manufactured in

The first model, known as the Pianette , was unique in that the tuning pins extended through the instrument, so it could be tuned at the front. The prepared piano , present in some contemporary art music from the 20th and 21st century is a piano which has objects placed inside it to alter its sound, or has had its mechanism changed in some other way. The scores for music for prepared piano specify

Moreover, there is some evidence that some non-human primates lack auditory cortex responses to pitch despite having clear tonotopic maps in auditory cortex, showing that tonotopic place codes are not sufficient for pitch responses. Temporal theories offer an alternative that appeals to the temporal structure of action potentials, mostly the phase-lock of action potentials to frequencies in
8400-408: The modifications, for example, instructing the pianist to insert pieces of rubber, paper, metal screws, or washers in between the strings. These objects mute the strings or alter their timbre. Some Viennese fortepianos incorporated percussion effects, brought into action by levers. These would be used in pieces such as Mozart's Rondo alla Turca . The pedal piano is a rare type of piano that has
8512-427: The most common type of clarinet or trumpet , when playing a note written in their part as C, sounds a pitch that is called B ♭ on a non-transposing instrument like a violin (which indicates that at one time these wind instruments played at a standard pitch a tone lower than violin pitch). To refer to that pitch unambiguously, a musician calls it concert B ♭ , meaning, "the pitch that someone playing
8624-500: The most visible change of any type of piano: the iron-framed, over-strung squares manufactured by Steinway & Sons were more than two-and-a-half times the size of Zumpe's wood-framed instruments from a century before. Their overwhelming popularity was the result of inexpensive construction and price, although their tone and performance were limited by narrow soundboards, simple actions and string spacing that made proper hammer alignment difficult. The tall, vertically strung upright grand
8736-410: The next generation of piano builders started their work based on reading this article. One of these builders was Gottfried Silbermann , better known as an organ builder. Silbermann's pianos were virtual copies of Cristofori's, with one important addition: Silbermann invented the forerunner of the modern sustain pedal , which lifts all the dampers from the strings simultaneously. This innovation allows
8848-404: The observer. When the actual fundamental frequency can be precisely determined through physical measurement, it may differ from the perceived pitch because of overtones , also known as upper partials, harmonic or otherwise. A complex tone composed of two sine waves of 1000 and 1200 Hz may sometimes be heard as up to three pitches: two spectral pitches at 1000 and 1200 Hz, derived from
8960-545: The opposite coloring of modern-day pianos; the natural keys were black and the accidental keys white. It was for such instruments that Wolfgang Amadeus Mozart composed his concertos and sonatas , and replicas of them are built in the 21st century for use in authentic-instrument performance of his music. The pianos of Mozart's day had a softer tone than 21st century pianos or English pianos, with less sustaining power. The term fortepiano now distinguishes these early instruments (and modern re-creations) from later pianos. In
9072-456: The output of the cochlea , as via auditory-nerve interspike-interval histograms. Some theories of pitch perception hold that pitch has inherent octave ambiguities, and therefore is best decomposed into a pitch chroma , a periodic value around the octave, like the note names in Western music—and a pitch height , which may be ambiguous, that indicates the octave the pitch is in. The just-noticeable difference (jnd) (the threshold at which
9184-420: The perception of pitch is determined by the place of maximum excitation on the basilar membrane . A place code, taking advantage of the tonotopy in the auditory system, must be in effect for the perception of high frequencies, since neurons have an upper limit on how fast they can phase-lock their action potentials . However, a purely place-based theory cannot account for the accuracy of pitch perception in
9296-467: The period from about 1790 to 1860, the Mozart-era piano underwent significant changes that led to the modern structure of the instrument. This revolution was in response to a preference by composers and pianists for a more powerful, sustained piano sound, which was made possible by the ongoing Industrial Revolution with resources such as high-quality piano wire for strings and precision casting for
9408-408: The physical frequencies of the pure tones, and the combination tone at 200 Hz, corresponding to the repetition rate of the waveform. In a situation like this, the percept at 200 Hz is commonly referred to as the missing fundamental , which is often the greatest common divisor of the frequencies present. Pitch depends to a lesser degree on the sound pressure level (loudness, volume) of
9520-437: The pianist to sustain the notes that they have depressed even after their fingers are no longer pressing down the keys. As such, by holding a chord with the sustain pedal, pianists can relocate their hands to a different register of the keyboard in preparation for a subsequent section. Silbermann showed Johann Sebastian Bach one of his early instruments in the 1730s, but Bach did not like the instrument at that time, saying that
9632-439: The pianist's touch (pressure on the keys): the greater the pressure, the greater the force of the hammer hitting the strings and the louder the sound produced and the stronger the attack . Invented in 1700, the fortepiano was the first keyboard instrument to allow gradations of volume and tone according to how forcefully or softly the player presses or strikes the keys, unlike the pipe organ and harpsichord. The invention of
9744-547: The piano is credited to Bartolomeo Cristofori of Padua , Italy, who was employed by Ferdinando de' Medici, Grand Prince of Tuscany , as the Keeper of the Instruments. Cristofori was an expert harpsichord maker and was well acquainted with the body of knowledge on stringed keyboard instruments. This knowledge of keyboard mechanisms and actions helped him to develop the first pianos. It is not known when Cristofori first built
9856-523: The player piano replays the performance using pneumatic devices. Modern equivalents of the player piano include the Bösendorfer CEUS, Yamaha Disklavier and QRS Pianomation, using solenoids and MIDI rather than pneumatics and rolls. A silent piano is an acoustic piano having an option to silence the strings by means of an interposing hammer bar. They are designed for private silent practice, to avoid disturbing others. Edward Ryley invented
9968-410: The preferred choice when space and budget allow. The grand piano is also considered a necessity in venues hosting skilled pianists. The upright piano is more commonly used because of its smaller size and lower cost. When a key is depressed, the strings inside are struck by felt-coated wooden hammers. The vibrations are transmitted through a bridge to a soundboard that amplifies the sound by coupling
10080-418: The production of massive iron frames that could withstand the tremendous tension of the strings. Over time, the tonal range of the piano was also increased from the five octaves of Mozart's day to the seven octave (or more) range found on today's pianos. Early technological progress in the late 18th century owed much to the firm of Broadwood . John Broadwood joined with another Scot, Robert Stodart, and
10192-450: The rim was constructed from several pieces of solid wood, joined and veneered, and European makers used this method well into the 20th century. A modern exception, Bösendorfer (an Austrian manufacturer of high-quality pianos) constructs their inner rims from solid spruce, the same wood that the soundboard is made from, which is notched to allow it to bend; rather than isolating the rim from vibration, their "resonance case principle" allows
10304-404: The so-called Baroque pitch , has been set in the 20th century as A = 415 Hz—approximately an equal-tempered semitone lower than A440 to facilitate transposition. The Classical pitch can be set to either 427 Hz (about halfway between A415 and A440) or 430 Hz (also between A415 and A440 but slightly sharper than the quarter tone). And ensembles specializing in authentic performance set
10416-403: The soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound." Hardwood rims are commonly made by laminating thin (hence flexible) strips of hardwood, bending them to the desired shape immediately after the application of glue. The bent plywood system was developed by C.F. Theodore Steinway in 1880 to reduce manufacturing time and costs. Previously,
10528-402: The soundboard is made of spruce boards glued together along the side grain. Spruce's high ratio of strength to weight minimizes acoustic impedance while offering strength sufficient to withstand the downward force of the strings. The best piano makers use quarter-sawn , defect-free spruce of close annular grain, carefully seasoning it over a long period before fabricating the soundboards. This
10640-511: The source of a sound is slightly higher or lower in vertical space when the sound frequency is increased or reduced. In most cases, the pitch of complex sounds such as speech and musical notes corresponds very nearly to the repetition rate of periodic or nearly-periodic sounds, or to the reciprocal of the time interval between repeating similar events in the sound waveform. The pitch of complex tones can be ambiguous, meaning that two or more different pitches can be perceived, depending upon
10752-417: The string, such as rust on plain strings and dirt in the windings of bass strings. The higher the partial, the further sharp it runs. Pianos with shorter and thicker string (i.e., small pianos with short string scales) have more inharmonicity. The greater the inharmonicity, the more the ear perceives it as harshness of tone. The inharmonicity of piano strings requires that octaves be stretched , or tuned to
10864-418: The strings are placed in two separate planes, each with its own bridge height, allowed greater length to the bass strings and optimized the transition from unwound tenor strings to the iron or copper-wound bass strings. Over-stringing was invented by Pape during the 1820s and first patented for use in grand pianos in the United States by Henry Steinway Jr. in 1859. Some piano makers added variations to enhance
10976-448: The strings when the sustain pedal is depressed, key release, the drop of the dampers, and simulations of techniques such as re-pedalling. Digital, MIDI-equipped pianos can output a stream of MIDI data, or record and play MIDI format files on digital storage media, similar in concept to a pianola. The MIDI file records the physics of a note rather than its resulting sound and recreates the sounds from its physical properties (e.g., which note
11088-464: The strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials or harmonics ) sound sharp relative to whole multiples of the fundamental frequency. This results from the piano's considerable string stiffness; as a struck string decays, its harmonics vibrate from a point very slightly from its termination toward the center (or more flexible part) of the string. The inharmonicity may also result from imperfections within
11200-437: The sustain pedal is depressed) and full pedal sets can now be replicated. The processing power of digital pianos has enabled highly realistic pianos using multi-gigabyte piano sample sets with as many as ninety recordings, each lasting many seconds, for each key under different conditions (e.g., there are samples of each note being struck softly, loudly, with a sharp attack, etc.). Additional samples emulate sympathetic resonance of
11312-415: The tone of each note, such as Pascal Taskin (1788), Collard & Collard (1821), and Julius Blüthner , who developed Aliquot stringing in 1893. These systems were used to strengthen the tone of the highest register of notes on the piano, which up until this time were viewed as being too weak-sounding. Each used more distinctly ringing, undamped vibrations of sympathetically vibrating strings to add to
11424-489: The tone, especially at frequencies below 1,000 Hz and above 2,000 Hz. The pitch of lower tones gets lower as sound pressure increases. For instance, a tone of 200 Hz that is very loud seems one semitone lower in pitch than if it is just barely audible. Above 2,000 Hz, the pitch gets higher as the sound gets louder. These results were obtained in the pioneering works by S. Stevens and W. Snow. Later investigations, e.g. by A. Cohen, have shown that in most cases
11536-550: The tone, except the Blüthner Aliquot stringing , which uses an additional fourth string in the upper two treble sections. While the hitchpins of these separately suspended Aliquot strings are raised slightly above the level of the usual tri-choir strings, they are not struck by the hammers but rather are damped by attachments of the usual dampers. Eager to copy these effects, Theodore Steinway invented duplex scaling , which used short lengths of non-speaking wire bridged by
11648-399: The two tones are played simultaneously as the listener is then able to discern beat frequencies . The total number of perceptible pitch steps in the human hearing range is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120. The relative perception of pitch can be fooled, resulting in aural illusions . There are several of these, such as
11760-448: The wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation. Despite that, the idiom relating vertical height to sound pitch is shared by most languages. At least in English, it is just one of many deep conceptual metaphors that involve up/down. The exact etymological history of the musical sense of high and low pitch is still unclear. There is evidence that humans do actually perceive that
11872-408: The way the piano was strung. There are one string for each note in the bass, two for each note in the tenor, and three for each note in the tenor. The use of a Capo d’Astro bar instead of agraffes in the uppermost treble allowed the hammers to strike the strings in their optimal position, greatly increasing that area's power. The implementation of over-stringing (also called cross-stringing ), in which
11984-475: The west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach , for example), different methods of musical tuning were used. In almost all of these systems interval of
12096-424: Was arranged like a grand set on end, with the soundboard and bridges above the keys and tuning pins below them. " Giraffe pianos ", " pyramid pianos " and " lyre pianos " were arranged in a somewhat similar fashion, using evocatively shaped cases. The very tall cabinet piano was introduced about 1805 and was built through the 1840s. It had strings arranged vertically on a continuous frame with bridges extended nearly to
12208-537: Was designing a stringed keyboard instrument in which the notes are struck by a hammer. The hammer must strike the string but not remain in contact with it, because continued contact would damp the sound and stop the string from vibrating and making sound. This means that after striking the string, the hammer must quickly fall from (or rebound from) the strings. Moreover, the hammer must return to its rest position without bouncing violently (thus preventing notes from being re-played by accidental rebound), and it must return to
12320-411: Was manufactured from the mid-1930s until recent times. The low position of the hammers required the use of a "drop action" to preserve a reasonable keyboard height. Modern upright and grand pianos attained their present, 2000-era forms by the end of the 19th century. While improvements have been made in manufacturing processes, and many individual details of the instrument continue to receive attention, and
12432-494: Was struck and with what velocity). Computer based software, such as Modartt's 2006 Pianoteq , can be used to manipulate the MIDI stream in real time or subsequently to edit it. This type of software may use no samples but synthesize a sound based on aspects of the physics that went into the creation of a played note. By the 2000s, some pianos included an acoustic grand piano or upright piano combined with MIDI electronic features. Such
12544-403: Was the first to use in pianos in 1826, was a more consistent material, permitting wider dynamic ranges as hammer weights and string tension increased. The sostenuto pedal ( see below ), invented in 1844 by Jean-Louis Boisselot and copied by the Steinway firm in 1874, allowed for a wider range of effects. One innovation that helped create the powerful sound of the modern piano was the use of
