34-518: The hybrid term subharmonic is used in music in a few different ways. In its pure sense, the term subharmonic refers strictly to any member of the subharmonic series ( 1 ⁄ 1 , 1 ⁄ 2 , 1 ⁄ 3 , 1 ⁄ 4 , etc.). When the subharmonic series is used to refer to frequency relationships, it is written with f representing some highest known reference frequency ( f ⁄ 1 , f ⁄ 2 , f ⁄ 3 , f ⁄ 4 , etc.). As such, one way to define subharmonics

68-430: A wind instrument , or by dividing a monochord string. If a monochord string is lightly damped at the halfway point, then at 1 ⁄ 3 , then 1 ⁄ 4 , 1 ⁄ 5 , etc., then the string will produce the overtone series, which includes the major triad . If instead, the length of the string is multiplied in the opposite ratios, the undertones series is produced. Vocal subharmonics or subharmonic singing

102-403: A finger lightly on a string at certain locations). In a very loose third sense, subharmonic is sometimes used or misused to represent any frequency lower than some other known frequency or frequencies, no matter what the frequency relationship is between those frequencies and no matter the method of production. The overtone series can be produced physically in two ways – either by overblowing

136-534: A generator with upper major third and perfect fifth, the minor chord consists of a generator with lower major third and fifth. Hermann von Helmholtz observed in On the Sensations of Tone that the tone of a string tuned to C on a piano changes more noticeably when the notes of its undertone series (C, F, C, A ♭ , F, D, C, etc.) are struck than those of its overtones. Helmholtz argued that sympathetic resonance

170-400: A mirror image of the harmonic series , the overtone series. In the overtone series, if we consider C as the fundamental, the first five notes that follow are: C (one octave higher), G ( perfect fifth higher than previous note), C ( perfect fourth higher than previous note), E ( major third higher than previous note), and G ( minor third higher than previous note). The pattern occurs in

204-478: A non-Semitic descent suffix: The following Modern Hebrew hybrid words have an international prefix: Some hybrid words consist of both a non-Hebrew word and a non-Hebrew suffix of different origins: Some hybrid words consist of a non-Hebrew word and a Hebrew suffix: Modern Hebrew also has a productive derogatory prefixal shm- , which results in an 'echoic expressive'. For example, um shmum ( או״ם־שמו״ם ‎), literally 'United Nations shm-United Nations',

238-472: A page with interlocking over- and undertone series. Kathleen Schlesinger pointed out, in 1939, that since the ancient Greek aulos , or reed-blown flute, had holes bored at equal distances, it must have produced a section of the undertone series. She said that this discovery not only cleared up many riddles about the original Greek modes, but indicated that many ancient systems around the world must have also been based on this principle. One area of conjecture

272-401: A pattern is seen: The undertone series in C contains the F minor triad. Elizabeth Godley argued that the minor triad is also implied by the undertone series and is also a naturally occurring thing in acoustics . "According to this theory the upper and not the lower tone of a minor chord is the generating tone on which the unity of the chord is conditioned." Whereas the major chord consists of

306-469: A similar token, analog synthesizers such as the Serge synthesizer and many modern Eurorack synthesizers can produce undertone series as a side effect of the solid state timing circuits (e.g. the 555 timer IC ) in their envelope generators not being able to re-trigger until their cycle is complete. As an example, sending a clock of period N into an envelope generator where the sum of the rise and fall time

340-418: A subharmonic resonant tone of the unplugged part of the string. Subharmonics can be produced by signal amplification through loudspeakers . They are also a common effect in both digital and analog signal processing . Octave effect processors synthesize a subharmonic tone at a fixed interval to the input. Subharmonic synthesizer systems used in audio production and mastering work on the same principle. By

374-414: A way still resemble the harmonic series, not the subharmonic series. In this sense, subharmonic is a term created by reflection from the second sense of the term harmonic , which in that sense refers to an instrumental technique for making an instrument's pitch seem higher than normal by eliminating some lower partials by damping the resonator at the antinodes of vibration of those partials (such as placing

408-417: Is a vocal technique that lets singers produce notes below the fundamental and follows the undertone series. It can extend down from the regular vocal range an octave and further below when well controlled. It can be described as having a stable vocal fry -like sound. These pitches are produced by a combination of oscillations of turbulent airflow in the vocal tract. Coming from multiple sound sources such as

442-491: Is an experimental guitar invented in 2003 by mathematicians Samuel Gaudet and Claude Gauthier of the Université de Moncton of a family of stringed instruments which use Y -shaped strings, instead of the usual linear strings. Y-shaped strings can produce sounds which are harmonic integer multiples, but also non-harmonic sounds more akin to those produced by percussion instruments. The model uses 6 strings and

476-537: Is at least as active in under partials as in over partials. Henry Cowell discusses a "Professor Nicolas Garbusov of the Moscow Institute for Musicology" who created an instrument "on which at least the first nine undertones could be heard without the aid of resonators." The phenomenon is described as occurring in resonators of instruments; First proposed by Zarlino in Instituzione armoniche (1558),

510-505: Is from English and "-ado" is from Khoribari In Japanese , hybrid words are common in kango (words formed from kanji characters) in which some of the characters may be pronounced using Chinese pronunciations ( on'yomi, from Chinese morphemes), and others in the same word are pronounced using Japanese pronunciations ( kun'yomi, from Japanese morphemes). These words are known as jūbako (重箱) or yutō (湯桶), which are themselves examples of this kind of compound (they are autological words ):

544-502: Is greater than 2 N and less than 3 N would result in an output waveform that tracks at 1 ⁄ 3 of the frequency of the input clock. Subharmonic frequencies are frequencies below the fundamental frequency of an oscillator in a ratio of 1/ n , with n a positive integer . For example, if the fundamental frequency of an oscillator is 440 Hz, sub-harmonics include 220 Hz ( 1 ⁄ 2 ), ~146.6 Hz ( 1 ⁄ 3 ) and 110 Hz ( 1 ⁄ 4 ). Thus, they are

578-414: Is straightforward to add a prefix or suffix from one language to an English word that comes from a different language, thus creating a hybrid word . Hybridisms were formerly often considered to be barbarisms . Modern Hebrew abounds with non- Semitic derivational affixes, which are applied to words of both Semitic and non-Semitic descent. The following hybrid words consist of a Hebrew-descent word and

612-475: Is that the undertone series might be part of the compositional design phase of the compositional process. The overtone and undertone series can be considered two different arrays, with smaller arrays that contain different major and minor triads. Most experiments with undertones to date have focused largely upon improvisation and performance not compositional design (for example the recent use of negative harmony in jazz, popularised by Jacob Collier and stemming from

646-520: Is that they are "... integral submultiples of the fundamental (driving) frequency". The complex tones of acoustic instruments do not produce partials that resemble the subharmonic series, unless they are played or designed to induce non-linearity. However, such tones can be produced artificially with audio software and electronics. Subharmonics can be contrasted with harmonics . While harmonics can "... occur in any linear system", there are "... only fairly restricted conditions" that will lead to

680-644: Is traceable back to Yiddish , and is found in English as well as shm-reduplication . This is comparable to the Turkic initial m-segment conveying a sense of 'and so on' as in Turkish dergi mergi okumuyor , literally 'magazine "shmagazine" read:NEGATIVE:PRESENT:3rd.person.singular', i.e. '(He) doesn't read magazine, journals or anything like that'. In Filipino , hybrid words are called siyokoy (literally "merman"). For example, concernado ("concerned"): "concern-"

714-432: The "nonlinear phenomenon known as subharmonic generation". In a second sense, subharmonic does not relate to the subharmonic series, but instead describes an instrumental technique for lowering the pitch of an acoustic instrument below what would be expected for the resonant frequency of that instrument, such as a violin string that is driven and damped by increased bow pressure to produce a fundamental frequency lower than

748-592: The first character of jūbako is read using on'yomi , the second kun'yomi , while it is the other way around with yutō . Other examples include 場所 basho "place" ( kun-on ), 金色 kin'iro "golden" ( on-kun ) and 合気道 aikidō "the martial art Aikido " ( kun-on-on ). Some hybrid words are neither jūbako nor yutō (縦中横 tatechūyoko ( kun-on-kun )). Foreign words may also be hybridized with Chinese or Japanese readings in slang words such as 高層ビル kōsōbiru "high-rise building" ( on-on-katakana ) and 飯テロ meshitero "food terrorism" ( kun-katakana ). Tritare A tritare

782-634: The history of these two series, as well as the main other system created by the circle of fifths , and argues that in hidden form, the series are balanced out in Bach 's harmony. Hybrid word A hybrid word or hybridism is a word that etymologically derives from at least two languages. Such words are a type of macaronic language . The most common form of hybrid word in English combines Latin and Greek parts. Since many prefixes and suffixes in English are of Latin or Greek etymology , it

816-607: The lowest open string on the instrument." These require string instrument players to bow with sufficient pressure that the strings vibrate in a manner causing the sound waves to modulate and demodulate by the instrument's resonating horn with frequencies corresponding to subharmonics. The tritare , a guitar with Y-shaped strings, cause subharmonics too. This can also be achieved by the extended technique of crossing two strings as some experimental jazz guitarists have developed. Also third bridge preparations on guitars cause timbres consisting of sets of high pitched overtones combined with

850-431: The minor triad is usually heard as sad, or at least pensive, because humans habitually hear all chords as based from below. If feelings are instead based on the high "fundamental" of an undertone series, then descending into a minor triad is not felt as melancholy, but rather as overcoming, conquering something. The overtones, by contrast, are then felt as penetrating from outside. Using Rudolf Steiner 's work, Jackson traces

884-406: The normal pitch of the same open string. The human voice can also be forced into a similar driven resonance, also called "undertone singing" (which similarly has nothing to do with the undertone series), to extend the range of the voice below what is normally available. However, the frequency relationships of the component partials of the tone produced by the acoustic instrument or voice played in such

918-454: The overtone and undertone series must be seen as a real polarity, representing on the one hand the outer "material world" and on the other, our subjective "inner world". This view is largely based on the fact that the overtone series has been accepted because it can be explained by materialistic science, while the prevailing conviction about the undertone series is that it can only be achieved by taking subjective experience seriously. For instance,

952-405: The overtone series. This assertion rests on the fact that undertones do not sound simultaneously with its fundamental tone as the overtone series does. In 1868, Adolf von Thimus showed that an indication by a 1st-century Pythagorean, Nicomachus of Gerasa , taken up by Iamblichus in the 4th century, and then worked out by von Thimus, revealed that Pythagoras already had a diagram that could fill

986-564: The research of Ernst Levy ), although in 1985/86 Jonathan Parry used what he called the Inverse Harmonic Series (identical to the Undertone Series) as one stage in his process of Harmonic Translation. Harry Partch argued that the overtone series and the undertone series are equally fundamental, and his concepts of Otonality and Utonality is based on this idea. Similarly, in 2006 G.H. Jackson suggested that

1020-409: The same manner using the undertone series. Again we will start with C as the fundamental. The first five notes that follow will be: C (one octave lower), F ( perfect fifth lower than previous note), C ( perfect fourth lower than previous note), A ♭ ( major third lower than previous note), and F ( minor third lower than previous note). If the first five notes of both series are compared,

1054-461: The true and false vocal chords. Singers often describe it as feeling like stable points below regularly sung notes where it snaps or jumps specific intervals. This technique might also happen by accident when talking or singing in a fry voice. String quartets by composers George Crumb and Daniel James Wolf , as well as works by violinist and composer Mari Kimura , include undertones, "produced by bowing with great pressure to create pitches below

1088-423: The undertone series has been appealed to by theorists such as Riemann and D'Indy to explain phenomena such as the minor chord , that they thought the overtone series would not explain. However, while the overtone series occurs naturally as a result of wave propagation and sound acoustics , musicologists such as Paul Hindemith considered the undertone series to be a purely theoretical 'intervallic reflection' of

1122-532: Was a pejorative description by Israel's first Prime Minister, David Ben-Gurion , of the United Nations , called in Modern Hebrew umot meukhadot ( אומות מאוחדות ‎) and abbreviated um ( או״ם ‎). Thus, when a Hebrew speaker would like to express his impatience with or disdain for philosophy, s/he can say filosófya- shm ilosófya ( פילוסופיה־שמילוסופיה ‎). Modern Hebrew shm-

1156-482: Was commercially available for a short period. The sound effects achieved with the instrument are similar to the sounds that can be achieved with the 3rd bridge playing technique. When tuned correctly, the Y-shaped strings create Chladni patterns . Depending on how each note is played, Gaudet explains that non-harmonic ingredients can be included and offer a richer sound than a classical stringed instrument. However
