A concert band , also called a wind band , wind ensemble , wind symphony , wind orchestra , symphonic band , the symphonic winds , or symphonic wind ensemble , is a performing ensemble consisting of members of the woodwind , brass , and percussion families of instruments, and occasionally including the harp , double bass , or bass guitar . On rare occasions, additional, non-traditional instruments may be added to such ensembles such as piano , synthesizer , or electric guitar .

87-478: Concert band music generally includes original wind compositions, concert marches , transcriptions of orchestral arrangements, light music , and popular music . Though the concert band does have similar instrumentation to the marching band , a marching band's main purpose is to perform while marching. In contrast, a concert band usually performs as a stationary ensemble , though European ensembles often do both. The origins of concert band can be traced back to

174-432: A ceremonial role, entertaining troops and playing for the community. As its role shifted so too did its instrumentation. A wider range of instruments was employed to play transcriptions of orchestral works, the bulk of the early wind band repertoire. These military bands evolved into the modern drum and bugle corps and helped to spread the idea of a concert band. A modern military will often have multiple types of bands (e.g.

261-618: A defined season at all. They practice and perform as they deem necessary or possible. Occasionally such corps make exhibition appearances at DCI or DCA shows. While on tour, junior corps travel mainly at night after leaving the performance venue. Members sleep on the buses and in sleeping bags on gym floors when the next housing destination is reached. Housing for the entire tour is secured in advance through local schools, churches, or other community facilities. Corps practice their shows for as long as possible each day before getting ready to leave for that night's competition if scheduled. Not every day

348-414: A feedback loop. These two elements are coupled at the flue exit and at the labium. At the flue exit the transversal acoustic flow of the pipe perturbs the jet. At the labium the jet oscillation results in a generation of acoustic waves, which maintain the pipe oscillation. The acoustic flow in the pipe can for a steady oscillation be described in terms of standing waves . These waves have a pressure node at

435-402: A flute can be described by a lumped element model in which the pipe acts as an acoustic swing (mass-spring system, resonator ) that preferentially oscillates at a natural frequency determined by the length of the tube. The instability of the jet acts as an amplifier transferring energy from the steady jet flow at the flue exit to the oscillating flow around the labium. The pipe forms with the jet

522-436: A fraction of the corps that existed in the 60s and 70s remained, although several new corps, some of which have become very successful, did start up along the way. Freed from the traditional and more-restrictive judging rules of the late 1960s, corps began making innovative changes such as the use of B ♭ brass instruments, wide-ranging tempos, intricate asymmetric drill formations, elaborate guard costumes and props, and

609-523: A large wind ensemble. It wasn't until the early 20th century that composers began writing works for concert band. Concert band composers of this time were frustrated at the lack of quality music for bands, and as such, began writing and performing pieces to remedy this. One of the first and most important original works for concert band, First Suite for Band by Gustav Holst , was written in 1909. Other composers of this time period include Ralph Vaughan Williams , Richard Wagner , and Aaron Copland . Before

696-483: A new show each year, approximately 8–12 minutes in length, and refine it throughout the summer tour. Shows are performed on football fields and are judged in various musical and visual categories, or "captions". Musical repertoires vary widely among corps and include symphonic , jazz , big band , contemporary , rock , wind band , vocal , rap , Broadway , and Latin music , among other genres. Competitive junior corps usually spend between 10 and 15 weeks on tour over

783-771: A potential health risk. One 2011 study focused on brass and woodwind instruments observed "temporary and sometimes dramatic elevations and fluctuations in IOP". Another study found that the magnitude of increase in intraocular pressure correlates with the intraoral resistance associated with the instrument and linked intermittent elevation of intraocular pressure from playing high-resistance wind instruments to incidence of visual field loss. The range of intraoral pressure involved in various classes of ethnic wind instruments, such as Native American flutes , has been shown to be generally lower than Western classical wind instruments. Drum and bugle corps (modern) A modern drum and bugle corps

870-398: A single composer's material is featured. Corps have performed virtually every genre of music that can be fit for on-field adaptation, including jazz, new age, classical, and rock music. It is becoming increasingly common to hear the corps performing original music, composed specifically for the corps by their musical staff or consultants. The exclusive use of bell-front brass instrumentation

957-618: A single harmonic series. Until 1999, drum and bugle corps horn lines within DCI were required to be pitched in the key of G. That year, the DCI rules congress passed a rule change to allow "brass bell-front valve instruments in any key with the exception of sousaphones and trombones." In World Class, the rule did not go into effect until the 2000 season, while Open Class opted for a two-year moratorium prior to implementation in 2002; DCA followed suit in 2004. Hornlines are now most commonly pitched in B ♭ , with mellophones pitched in F. In 2014,

1044-404: A weekend. For this reason, and to boost audience attendance, large competitions are more frequently scheduled on weekends. A typical regular-season contest consists of fewer than 10 corps, with corps from one or more classes competing together but scored separately. In North America, DCI and DCA corps occasionally perform at the same shows. DCI also schedules larger contests interspersed throughout

1131-414: A well-run corps is just like a well-run business. It requires many people to handle fiscal and operational responsibilities. There are four levels of staff operating a drum corps: Executive Management , Executive Staff , Instructional , and Volunteer . Each plays an essential role in creating a well-run corps. The executive management consists of the board of directors and the executive director. Often

1218-402: A wide variety of other auxiliary instruments such as hammered dulcimer . Since the keyboard instruments do not project as well as brass or marching percussion, they are often amplified to produce adequate sound. Due to the size of these instruments, the pit typically remains stationary, positioned directly in front of the field and centered on or around the 50-yard line. However, some groups use

1305-414: Is a musical instrument that contains some type of resonator (usually a tube) in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound

1392-516: Is a concert band or brass band ensemble composed of volunteer (non-paid) amateur musicians in a particular geographic area. It may be sponsored by the local (municipal) government or self-supporting. These groups rehearse regularly and perform at least once a year. Some bands are also marching bands , participating in parades and other outdoor events. Although they are volunteer musical organizations, community bands may employ an artistic director ( conductor ) or various operational staff. The rise of

1479-448: Is a defining musical element of drum corps. Throughout the years, the horns used in drum corps have been changed from true, single-valved bugles to B ♭ brass instruments. While brass bugles in these competitive drum corps began as military signaling devices, successive modifications made them capable of greater ranges of music. These traditionally valveless, key-of-G bugles evolved to include pistons and rotors, gaining notes beyond

1566-523: Is a major difference between the orchestra (which usually lacks a large battery of percussion) and the concert band. While in older transcriptions and concert works, the timpani were treated as their own section as in an orchestra, today in bands the timpani are considered a part of the percussion section. Consequently, the timpani player often will double on other percussion instruments. Contemporary compositions often call on players to use unusual instruments or effects. For example, several pieces call on

1653-723: Is a musical marching unit consisting of brass instruments , percussion instruments , electronic instruments , and color guard. Typically operating as independent non-profit organizations , corps perform in competitions, parades, festivals, and other civic functions. Participants of all ages are represented within the corps activity, but the majority are between the ages of 13 and 22 and are members of corps within Drum Corps International. Competitive summer drum corps participate in summer touring circuits, such as Drum Corps International (DCI) and Drum Corps Associates (DCA) [Now recognized as DCI All-age ] Corps prepare

1740-459: Is a performance day; many days on tour are spent simply traveling to a distant location or entirely on the practice field. A full-sized, adequately funded junior corps will have a fleet of vehicles, including three or more coach buses for members and staff, a truck or van to carry souvenirs that are sold at shows, and two semi-trucks, one for show equipment and one that serves as a kitchen on wheels. Most meals for all members and staff are provided by

1827-423: Is also producing the aeolian sound of a cylinder placed normal to an air-flow (singing wire phenomenon). In all these cases (flute, edgetone, aeolian tone...) the sound production does not involve a vibration of the wall. Hence the material in which the flute is made is not relevant for the principle of the sound production. There is no essential difference between a golden or a silver flute. The sound production in

1914-415: Is another technique used, most often at slower tempos. As an alternative, there are four major groups which utilize a bent leg technique ( Santa Clara Vanguard , Madison Scouts , Pacific Crest , and Guardians), in which the feet come off of the ground and move in a bicycle type motion. Marching technique programs have largely been inspired by dance technique. Terminology from ballet and high school band

2001-599: Is both to limit the difficulty for inexperienced players and because schools frequently do not have access to the less common instruments. The standard concert band will have several players on each part depending on available personnel and the preference of the conductor. A concert band can theoretically have as many as 200 members from a set of only 35 parts. The wind ensemble, on the other hand, will have very little doubling, if any; commonly, clarinets or flutes may be doubled, especially to handle any divisi passages , and others will have one player per part, as dictated by

2088-517: Is divided by two is divided by two The timing and organization of contests varies significantly from circuit to circuit. Only large DCI corps typically have the funding and time commitment from members to participate in DCI's touring circuit, where corps spend the majority of the summer traveling around the continent performing at different local and regional contests. In other circuits, and for smaller DCI corps, competitions are usually scheduled to allow corps to travel, perform, and return home within

2175-532: Is produced by blowing through a reed; others require buzzing into a metal mouthpiece, while yet others require the player to blow into a hole at an edge, which splits the air column and creates the sound. Almost all wind instruments use the last method, often in combination with one of the others, to extend their register. Wind instruments are typically grouped into two families: Woodwind instruments were originally made of wood, just as brass instruments were made of brass, but instruments are categorized based on how

2262-551: Is used to describe foot placement and positioning, and members of the color guard and hornline often jazz run in order to maintain upper body stability when moving at fast tempos with large step sizes. While performances and competitions only occur during the summer, preparation for the next season starts as soon as the last one ends. Corps activity of some sort goes on year-round. Months in advance of next season's first camp, corps begin assembling their staffs, choosing their musical repertoires, writing drill, etc. For junior corps,

2349-464: The American Legion . Owing to many of these groups' roots, corps were traditionally militaristic. By the late 1960s, many corps wanted more creative freedom and better financial compensation than was offered by their sponsoring organizations. Some felt the prize-money structures, based on competitive placement, were not fairly compensating all corps for their appearances. Additionally, some felt

2436-513: The Fourth of July weekend, corps often locate themselves in large metro areas so they can participate in more than one parade. Competitions are usually held at college or high school football stadiums or similar venues, and are scored by circuit-approved judges. Most circuits follow the three-caption system of General Effect (GE), Visual, and Music, with GE carrying the most weight. This is the scoring system currently used by DCI (others are similar):

2523-719: The Tokyo Kosei Wind Orchestra and Osaka Municipal Symphonic Band , as well as the Kappa Kappa Psi and Tau Beta Sigma Commissioning Program , the longest-running commissioning series for wind band in the United States. Some of the most important people in establishing literature written specifically for concert band in the early and middle 20th century were: Over the last fifty years, many composers have written major works for wind ensemble. Some rose to prominence for helping to develop

2610-556: The United States Marine Corps has both a drum and bugle corps and wind ensemble ). Professional concert bands not associated with the military appear across the globe, particularly in developed countries. However, most do not offer full-time positions. The competition to make it into one of these concert bands is incredibly high and the ratio of performers to entrants is narrowly small. Examples of professional non-military concert bands include: A community band

2697-464: The resonances of the instrument. On woodwinds, most notes vent at the uppermost open tone holes; only the lowest notes of each register vent fully or partly at the bell, and the bell's function in this case is to improve the consistency in tone between these notes and the others. Playing some wind instruments, in particular those involving high breath pressure resistance, produce increases in intraocular pressure , which has been linked to glaucoma as

2784-400: The vibrational modes depends on the speed of sound in air, which varies with air density . A change in temperature, and only to a much smaller degree also a change in humidity, influences the air density and thus the speed of sound, and therefore affects the tuning of wind instruments. The effect of thermal expansion of a wind instrument, even of a brass instrument, is negligible compared to

2871-472: The 1950s, wind ensembles included various combinations of instruments. The modern "standard" instrumentation of the wind ensemble was more or less established by Frederick Fennell at Eastman School of Music as the Eastman Wind Ensemble in 1952 after the model of the orchestra : a pool of players from which a composer can select in order to create different sonorities. According to Fennell,

2958-554: The 19th century, large ensembles of wind and percussion instruments in the British and American traditions existed mainly in the form of the military band for ceremonial and festive occasions, and the works performed consisted mostly of marches . The only time wind bands were used in a concert setting comparable to that of a symphony orchestra was when transcriptions of orchestral or operatic pieces were arranged and performed, as there were comparatively few original concert works for

3045-400: The 20th century, there was little music written specifically for the wind band, which led to an extensive repertoire of pieces transcribed from orchestral works, or arranged from other sources. However, as the wind band moved out of the sole domain of the military marching ensemble and into the concert hall, it has gained favor with composers, and now many works are being written specifically for

3132-465: The DCI Board of Directors passed a rule change that changed their definition of a bugle to allow the entire brass family, including trombones and concert French horns. The percussion section consists of two subsections: the front ensemble (also known as "pit") and the battery (also known as the "drumline"). Front ensemble members perform on orchestral percussion , electronic instruments , and

3219-573: The French Revolution, in which large bands would often gather for patriotic festivals and celebrations. These bands would play popular music that would immediately captivate the public's attention. Throughout the French Revolution, however, serious composers were often not interested in composing music for bands; this was due in large part to the instrumentation. Concert bands were (and still are) not standardized in their required type and number of instruments, making it nearly impossible to write

3306-477: The board are unpaid volunteers. This group is almost always long-standing within successful corps. They create the long-term vision and strategy for the organization, handling the financial, operational, and organizational issues to keep the corps running. The board of directors may be composed of alumni and other closely affiliated people. They hire the Executive (operational) Director who is responsible for hiring

3393-478: The center of attention, and visually reinforce the choreography. As visual programs have increased in complexity, corps have developed and formalized various movement techniques, the goal of each being the achievement of fluid, consistent movements that allow for precise musical technique at all tempos, step sizes, and directions. Given that instrument-wielding members most often face toward the audience (for maximum sound projection), marching technique must not affect

3480-443: The championships are often the only time all corps in a class compete together. Some circuits also organize optional individual and ensemble (I&E) competitions for individuals or groups from corps to showcase members' skills outside the field performance environment. These are usually held only once or twice per season at championships or a major regional contest. Members practice their routine(s) in their scant free time throughout

3567-431: The color guard has become a crucial part of each group's visual and thematic program. Standard equipment includes silk flags, non-functioning rifles, and sabres, and other objects like bare poles, hoops, balls, windsocks, and custom-made props are sometimes used to create visual effects that enhance the show. The primary role of the color guard is to complement the corps' musical program by creating visual interpretations of

3654-413: The common level would be open to anyone. For example, in many U.S. high schools, "Concert Band" refers to the introductory level band, "Symphonic Band" is the title for the intermediate level band, and "Wind Ensemble" is the title for the advanced level band. Instrumentation for the wind band is not completely standardized; composers will frequently add or omit parts. Instruments and parts in parentheses in

3741-777: The community band as graduates sought to play in a band together again. Notable community bands include: U.S.A. United Kingdom Canada Australia Norway Portugal Finland A school band is a group of student musicians who rehearse and perform instrumental music together. A school band is usually under the direction of one or more conductors (band directors). A school band consists of woodwind instruments , brass instruments and percussion instruments, although upper level bands may also have string basses or bass guitar . In many traditional U.S. high schools, there are multiple band levels, distinguished by skill level or other factors. In such schools, an audition may be required to advance to further band levels, while

3828-573: The community band can partially be attributed to industrialization. As the instruments became easier to manufacture, their availability greatly increased. This meant that many amateurs could now form a town band, their arrangements typically consisting of patriotic tunes, marches, and popular music. The American Civil War marked a turning point in the American community band where many military musicians, either stemming from amateur or professional backgrounds, sought to create their own community band after

3915-590: The concert band and the wind ensemble. While today there are composers who write exclusively for band, it is worth noting that many composers famous for their work in other genres have given their talents to composition for wind bands as well. This is especially true in Japan, where an enormous market can be found for wind band compositions, which is largely due to commissions by the All-Japan Band Association and leading professional ensembles such as

4002-1286: The concert band. Research on wind-band topics began in earnest in 1964 through the Journal of Band Research , affiliated with the American Bandmasters Association . During the early 21st century, organizations that promote band research began publishing more research on wind band-related topics: Germany-based IGEB (founded 1974), the World Association of Symphonic Bands and Ensembles (WASBE, founded 1983), and US-based organizations Historic Brass Society (founded 1988), National Band Association (NBA, founded 1960), and College Band Directors National Association (CBDNA, founded 1941). Internationally notable wind-band researchers include Vincent Dubois on French bands, Paul Niemisto on Finnish bands, Frederick Harris on wind-band conductors, Jill M. Sullivan on US women's bands, Frank Battisti on US bands, David Hebert on Japanese and Polynesian bands, Patrick M. Jones on US military bands, and David Whitwell on European bands and repertoire. Some notable band associations include: Wind instrument A wind instrument

4089-448: The cook truck, but occasionally corps have scheduled free days where there are no rehearsals or performances and the members are free to see some local sights and procure their own meals. Competitions are not the only performances that corps partake in while on tour. Most corps also participate in parades and standstill performances throughout the summer to gain further public exposure and to supplement their budget with performance fees. On

4176-405: The corps that remained, longer travel times were necessary to attend the shrinking numbers of contests, further adding to the financial and time demands on the organizations and their individual members. At the same time costs for the increasingly complex field shows mounted and creative and instructional demands rose leading many competitive corps to falter and become inactive. By the late 1990s only

4263-466: The correct number of parts for the correct types of instruments. The quality of instruments also impacted composers' unwillingness to compose music for concert band. Wind instruments at that time were often difficult to play in tune and had difficulty in switching pitch and rhythm fast enough. This in turn influenced bands to stick with pieces that were transposed from orchestral movements and arrangements, something that has carried into modern day. During

4350-659: The current judging rules were stifling musical and theatrical possibilities. At the peak of North American drum corps participation (with perhaps a thousand active corps in the U.S. and nearly as many in Canada), several corps decided to "unionize", as stated by Don Warren (founder of the Cavaliers ). They formed their own organizations, which ultimately led to the formation of Drum Corps Associates (DCA) in 1965 and Drum Corps International (DCI) in 1972. By this time, many corps had already lost their church or community sponsors. For

4437-520: The end of World War I, advancements in radio technology rendered using drum and bugle corps for communication obsolete. When the war concluded in 1918, there was no longer a need for these instruments. The instruments were sold to veteran organizations such as the Veterans of Foreign Wars (VFW) and the newly founded American Legion (AL) . These veteran organizations would become the first sponsors of civilian drum and bugle corps. The veteran's initial goal

4524-403: The executive staff, the instructional staff, and recruiting volunteers. The executive staff usually includes the operational office staff, the program director(s) and tour director(s) who run the day-to-day operational needs of the organization. The instructional staff puts the show on the field. They create the concept of the show, choose and arrange the music, write the drill, and instruct

4611-493: The family of brass instruments because the vibration is initiated by the player's lips. In the Hornbostel-Sachs scheme of musical instrument classification , wind instruments are classed as aerophones . Sound production in all wind instruments depends on the entry of air into a flow-control valve attached to a resonant chamber ( resonator ). The resonator is typically a long cylindrical or conical tube, open at

4698-400: The far end. A pulse of high pressure from the valve will travel down the tube at the speed of sound . It will be reflected from the open end as a return pulse of low pressure. Under suitable conditions, the valve will reflect the pulse back, with increased energy, until a standing wave forms in the tube. Reed instruments such as the clarinet or oboe have a flexible reed or reeds at

4785-490: The fluid travels towards the labium. This results into a global transversal motion of the jet at the labium. The amplification of perturbations of a jet by its intrinsic instability can be observed when looking at a plume of cigarette smoke. Any small amplitude motion of the hand holding the cigarette results into an oscillation of the plume increasing with distance upwards and eventually a chaotic motion (turbulence). The same jet oscillation can be triggered by gentle air flow in

4872-449: The formations made by the performers on the field. Modern drill formations are much more complex and dynamic than the drill formations of early drum corps. Traditional blocks, company fronts, and symmetrical formations — while still utilized occasionally for impactful moments — have largely given way to more abstract and artistic designs. Drill writing at large is meant to keep instrumental sections together, put featured members at

4959-567: The front ensemble in creative ways by moving them around the field or putting them in different locations. A full-size front ensemble typically features 10 to 15 members. Members of the battery perform on marching percussion instruments, including snare drums , tenor drums (also known as "quads", "quints", or "tenors"), tonal bass drums , and cymbals. A full-size battery typically features 7–10 snare drummers, 3–6 tenor drummers, 5-6 bass drummers, and sometimes cymbal players, which tends to be 4-6 players in size. In modern drum corps,

5046-447: The hornline. Being visually oriented, guard members are not as bound to facing the front sideline, and may face any direction at any time as dictated by choreography. The most common backward marching technique requires balancing on one's platform (visually seen as the 'toes' and keeping the heels off the ground), which is especially effective at faster tempos. The reverse the heel–toe roll step, allowing for heel–ground contact

5133-408: The latter half of its season. These are restricted to corps in specific classes and feature many (if not all) of the corps within each class. European circuits, such as DCUK, operate on a "minimum performance and lot" system: appearance at the first two shows of the year is determined by lot, and then the corps must appear in a minimum number of shows before the circuit's championships. In such a system,

5220-462: The lips are most closed, and the air flow is lowest, when a low-pressure pulse arrives at the mouthpiece, to reflect a low-pressure pulse back down the tube. Standing waves inside the tube will be odd multiples of a quarter- wavelength , with a pressure anti-node at the mouthpiece, and a pressure node at the open end. For Air Reed ( flute and fipple -flute) instruments, the thin grazing air sheet (planar jet) flowing across an opening (mouth) in

5307-423: The list below are less common but still often used; due to the fact that some bands are missing these instruments, important lines for these instruments are often cued into other parts. Instrumentation differs depending on the type of ensemble. Middle school and high school bands frequently have more limited instrumentation and fewer parts (for example, no double reeds , or only two horn parts instead of four). This

5394-469: The members have been chosen and camps are held more frequently as the beginning of the summer touring season approaches. Most junior corps require their non-local members to secure temporary housing (often with local members or a vacant dormitory) near the corps' rehearsals facilities around Memorial Day weekend. For most of May and into June (as college and high school classes end), full-day rehearsals are held virtually every day so members can finish learning

5481-402: The members on their technique. The staff consists of brass, percussion, guard, and visual instructors who are most often alumni of the corps or other corps. A well-funded World Class corps usually has 15-20 full-time instructors. Just as members, they attend winter camps and travel with the corps all summer long. Volunteers are the lifeblood of any corps. Parents, alumni, friends, and fans make

5568-467: The mouth opening and another pressure node at the opposite open pipe termination. Standing waves inside such an open-open tube will be multiples of a half- wavelength . To a rough approximation, a tube of about 40 cm. will exhibit resonances near the following points: In practice, however, obtaining a range of musically useful tones from a wind instrument depends to a great extent on careful instrument design and playing technique. The frequency of

5655-417: The mouthpiece, forming a pressure-controlled valve. An increase in pressure inside the chamber will decrease the pressure differential across the reed; the reed will open more, increasing the flow of air. The increased flow of air will increase the internal pressure further, so a pulse of high pressure arriving at the mouthpiece will reflect as a higher-pressure pulse back down the tube. Standing waves inside

5742-823: The music and marching drill of the show. This pre-season "spring training" is usually 3–4 weeks long. It is not uncommon for members to rehearse 10–14 hours a day, 6–7 days a week throughout the entire pre-season. In mid to late June, corps leave to begin their summer tours. For all-age (formerly senior) corps, the process is not quite as grueling. Since most members have lives outside of drum corps, senior corps rehearse on weekends and occasionally on weekday evenings. Rather than extensive tours, senior corps usually take weekend trips to perform in shows, and make longer trips only to regional championships and finals. Many smaller DCI corps and foreign corps have similar itineraries. Non-competitive corps, such as classic-style corps, alumni corps, or newly aspiring corps might not have

5829-422: The music through choreographed dance. The color guard can also enhance the overall drill design by marching in formations that integrate with the rest of the corps. However, the color guard most often performs as an ensemble that frames the rest of the corps or performs within the drill formations of the corps proper. Like all other sections of the corps, the guard often features solo work. Drill formations refer to

5916-421: The nature of this type of sound source has been provided by Alan Powell when studying a planar jet interacting with a sharp edge in the absence of pipe (so called edgetone). The sound radiated from the edgetone can be predicted from a measurement of the unsteady force induced by the jet flow on the sharp edge (labium). The sound production by the reaction of the wall to an unsteady force of the flow around an object

6003-408: The older oboes and became more widely used in the 18th century. More heavy and bulky instruments were replaced by trombones and cornets . In the 19th century, band instruments became highly developed as they started to add keys and valves that made certain ranges and notes on instruments easier to navigate and perform, which became a huge game changer for all musicians. Until early in

6090-418: The oldest variety of military marching band in the world, dating from the 13th century. Military bands were originally used to control troops on the battlefield,By using instruments such as drums , bugles , and fifes among others. As communication systems during war became more advanced, the use of instruments on the battlefield as signaling devices fell out of use. From then on, military bands would fulfill

6177-399: The pipe interacts with a sharp edge (labium) to generate sound. The jet is generated by the player, when blowing through a thin slit (flue). For recorders and flue organ pipes this slit is manufactured by the instrument maker and has a fixed geometry. In a transverse flute or a pan flute the slit is formed by the musicians between their lips. Due to acoustic oscillation of the pipe the air in

6264-406: The pipe is alternatively compressed and expanded. This results in an alternating flow of air into and out of the pipe through the pipe mouth. The interaction of this transversal acoustic flow with the planar air jet induces at the flue exit (origin of the jet) a localised perturbation of the velocity profile of the jet. This perturbation is strongly amplified by the intrinsic instability of the jet as

6351-535: The requirements of a specific composition. It is also common to see two tubas and two euphoniums or baritones playing the same part in a wind ensemble. While largely made up of wind and percussion instruments, string instruments such as the string bass and concert harp are often scored for. The use of a harp dates back to its inclusion in the professional and military bands of John Philip Sousa and Edwin Franko Goldman . Such bands would often contain

6438-415: The rigidity of members' upper torsos. Although most horn players are able to follow this technique, members of the battery must keep their entire bodies facing forward at all times due to the nature of their equipment. This has led to the invention of the "crab walk" or oblique, where the legs cross over one another to facilitate sideways motion; the technique is used mostly by battery, but in rare instances by

6525-418: The room, which can be verified by waving with the other hand. The oscillation of the jet around the labium results into a fluctuating force of the airflow on the labium. Following the third law of Newton the labium exerts an opposite reaction force on the flow. One can demonstrate that this reaction force is the source of sound that drives the acoustic oscillation of the pipe. A quantitative demonstration of

6612-418: The season is a very intense process. Most corps begin having camps on or around Thanksgiving Day weekend and continue having monthly weekend camps throughout the winter. Potential members travel far and wide—literally from around the world—to attend the camps of their favorite corps. Membership in the top corps are highly competitive and are generally determined during the first few camps. By spring,

6699-469: The season. Most corps are operated as or by dedicated non-profit organizations; very few are associated with schools or for-profit entities. Some corps are even parts of larger non-profit performance arts organizations, which might also include theater groups, winter guards , winter drumlines , and other various musical or visual activities. In Europe, many are also registered charities, assisting with their fundraising aims. Despite their non-profit status,

6786-429: The sound is produced, not by the material used to construct them. For example, saxophones are typically made of brass, but are woodwind instruments because they produce sound with a vibrating reed . On the other hand, the didgeridoo , the wooden cornett (not to be confused with the cornet ), and the serpent are all made of wood (or sometimes plastic), and the olifant is made from ivory , but all of them belong to

6873-461: The summer, practicing and performing full-time. The term "modern" is used for the purposes of this article to differentiate it from classic drum and bugle corps , using the time period of the establishment of Drum Corps International as a dividing point in the timeline of the two types of drum and bugle corps. Modern drum and bugle corps stems from a rich American and Canadian military history, separate from other marching musical activities. Towards

6960-423: The thermal effect on the air. The bell of a wind instrument is the round, flared opening opposite the mouthpiece. It is found on clarinets, saxophones, oboes, horns, trumpets and many other kinds of instruments. On brass instruments, the acoustical coupling from the bore to the outside air occurs at the bell for all notes, and the shape of the bell optimizes this coupling. It also plays a major role in transforming

7047-704: The top harpists of the country, such as Winifred Bambrick , who was one of the first female instrumentalists to tour with the Sousa Band, and Victor Salvi , who played with the United States Navy Band . Notably, the United States Air Force Band scores for cellos , a practice unique to the ensemble that dates back to the tenure of director George S. Howard . Complicated percussion parts are common in concert band pieces, often requiring many percussionists. Many believe this

7134-399: The tube will be odd multiples of a quarter- wavelength , with a pressure anti-node at the mouthpiece, and a pressure node at the open end. The reed vibrates at a rate determined by the resonator . For Lip Reed ( brass ) instruments, the players control the tension in their lips so that they vibrate under the influence of the air flowing through them. They adjust the vibration so that

7221-500: The use of a siren while others will ask players to play recorders , whirly tubes , or to sing , hum , snap , clap or even crinkle sheets of paper . The wind band's diverse instrumentation and large number of players makes it a very flexible ensemble, capable of producing a variety of sonic effects. Instrumentation has developed throughout time to become more efficient for the conditions that marching bands need to play in. For example, clarinets were found to be more suitable than

7308-465: The use of stationary orchestral percussion instruments. A few corps still utilize the traditional G bugle which is very rarely found in DCI marching units. A typical show usually revolves around one genre of music, or sometimes melds separate genres together. Modern corps' programs have become increasingly conceptual and programmatic, with overarching show themes rather than loosely related musical selections. Often, especially within classical selections,

7395-494: The war's conclusion. The large number of bands created during this era led to a "Golden Age of Bands", spearheaded by conductors such as John Philip Sousa and Patrick Gilmore . The new forms of twentieth-century entertainment, namely the radio and phonograph , led to decline in community bands. This led to instrument manufacturers, who previously had marketed to the community bands, to focus on schools. The expansion of school music programs would eventually help restore interest in

7482-421: The wind ensemble was not revolutionary, but developed naturally out of the music. A military band is a group of personnel that performs musical duties for military functions, usually for the armed forces . A typical military band consists mostly of wind and percussion instruments. The conductor of a band commonly bears the title of Bandmaster or Director of Music . Ottoman military bands are thought to be

7569-546: Was finding ways to engage with their communities while maintaining a connection to military traditions and values. Drum and bugle corps became the perfect vehicle for adapting military musical traditions to civilian life. Beginning after World War I through the 1970s, corps and competitions were often sponsored by the VFW, Boy Scout troops , churches, fire departments, Rotary clubs , the Royal Canadian Legion , and
