Accordion

Accordions (from 19th-century German Akkordeon, from Akkord—'musical chord, concord of sounds') are a family of box-shaped musical instruments of the bellows-driven free reed aerophone type (producing sound as air flows past a reed in a frame), colloquially referred to as a squeezebox. The essential characteristic of the accordion is to combine in one instrument a melody section, also called the diskant, usually on the right-hand manual, with an accompaniment or Basso continuo functionality on the left-hand. The musician normally plays the melody on buttons or keys on the right-hand side (referred to as the manual), and the accompaniment on bass or pre-set chord buttons on the left-hand side. A person who plays the accordion is called an accordionist. The concertina and bandoneon are related, but do not have the diskant-accompaniment duality. The harmoneon is also related and, while having the descant vs. melody dualism, tries to make it less pronounced. The harmonium and American reed organ are in the same family, but are typically larger than an accordion and sit on a surface or the floor.

Acoustic bass guitar

The acoustic bass guitar (sometimes shortened to acoustic bass or initialized ABG) is a bass instrument with a hollow wooden body similar to, though usually larger than, a steel-string acoustic guitar. Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as on an electric bass guitar. Because it can sometimes be difficult to hear an acoustic bass guitar without an amplifier, even in settings with other acoustic instruments, most acoustic basses have pickups, either magnetic or piezoelectric or both, so that they can be amplified with a bass amp.

Acoustic guitar

An acoustic guitar is a musical instrument in the string family. When a string is plucked, its vibration is transmitted from the bridge, resonating throughout the top of the guitar. It is also transmitted to the side and back of the instrument, resonating through the air in the body, and producing sound from the sound hole. The original, general term for this stringed instrument is guitar, and the retronym 'acoustic guitar' distinguishes it from an electric guitar, which relies on electronic amplification. Typically, a guitar's body is a sound box, of which the top side serves as a sound board that enhances the vibration sounds of the strings. In standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4.

Adungu

The a'dungu, also called the ekidongo or ennenga, is a stringed musical instrument of the Alur people of northwestern Uganda. It is an arched harp of varying dimensions, ranging from seven to ten strings[citation needed] or more. The physical form of the a'dungu African harp derives from uniquely African origins. The instrument is made of a hollowed-out slab of wood, which is covered by two pieces of leather, woven together in the center. The upper piece of leather functions as a soundboard, and a wooden rib supports it, serving also as a structure to secure the strings to the soundboard. A curved wooden neck, containing a tuning peg for each note, is inserted into the end of the instrument's body. The strings run diagonally from the tuning pegs in the neck to the rib in the center of the body.

Aeolian harp

An Aeolian harp (also wind harp) is a musical instrument that is played by the wind. Named after Aeolus, the ancient Greek god of the wind, the traditional Aeolian harp is essentially a wooden box including a sounding board, with strings stretched lengthwise across two bridges. It is often placed in a slightly opened window where the wind can blow across the strings to produce sounds. The strings can be made of different materials (or thicknesses) and all be tuned to the same pitch, or identical strings can be tuned to different pitches. Besides being the only string instrument played solely by the wind, the Aeolian harp is also the only string instrument that plays solely harmonic frequencies. They are recognizable by the sound which is a result of this property, which has been described as eerie and ethereal.

Afoxé

The afoxé is an Afro Brazilian musical instrument composed of a gourd (cabaça) wrapped in a net in which beads or small plastic balls are threaded. The instrument is shaken to produce its musical noise. A similar instrument is the xequerê which is larger.

Agogo

An agogô (Yoruba: agogo, meaning bell) is a single or a multiple bell now used throughout the world but with origins in traditional Yoruba and Edo music and also in the samba baterias (percussion ensembles). The agogô may be the oldest samba instrument and was based on West African Yoruba single or double bells. The agogô has the highest pitch of any of the bateria instruments.

Agung

The agung is a set of two wide-rimmed, vertically suspended gongs used by the Maguindanao, Maranao, Sama-Bajau and Tausug people of the Philippines as a supportive instrument in kulintang ensembles. The agung is also ubiquitous among other groups found in Palawan, Panay, Mindoro, Mindanao, Sabah, Sulawesi, Sarawak and Kalimantan as an integral part of the agung orchestra. The agung is a large, heavy, wide-rimmed gong shaped like a kettle gong. of the agung produces a bass sound in the kulintang orchestra and weighs between 13 and 16 pounds, but it is possible to find agungs weigh as low as 5 pounds or as high as 20 or 30 pounds each, depending on the metal (bronze, brass or iron) used to produce them.

Air horn

An air horn is a pneumatic device designed to create an extremely loud noise for signaling purposes. It usually consists of a source which produces compressed air, which passes into a horn through a reed or diaphragm. The stream of air causes the reed or diaphragm to vibrate, creating sound waves, then the horn amplifies the sound making it louder. Air horns are widely employed as vehicle horns, installed on large buses, semi-trailer trucks, fire trucks, trains, and some ambulances as a warning device, and on ships as a signaling device.

Ajaeng

The ajaeng is a Korean string instrument. It is a wide zither with strings of twisted silk. It is played with a slender stick of forsythia wood that is drawn across the strings in the manner of a bow. The ajaeng mainly plays the bass part in ensemble music. And the ajaeng is divided into two types. The ajaeng used in court music is called jeongak ajaeng, and the ajaeng used in folk music is called sanjo ajaeng. The original version of the instrument, and that used in court music (called the jeongak ajaeng), has seven strings; while the ajaeng used for sanjo and sinawi (called the sanjo ajaeng) has eight. Some instruments have as many as nine to twelve strings.similar to the koto but bowed

Akkordolia

The akkordolia is a zither from Germany and Austria, consisting of a long box, with the strings being pressed against the fretboard by pressing down buttons from above, similar to the Japanese taishogoto. One row of buttons changes the melody, and the other row of buttons can change the chord which backs the melody.

Alboka

The Basque alboka (Spanish: albogue) is a single-reed woodwind instrument consisting of a single reed, two small diameter melody pipes with finger holes and a bell traditionally made from animal horn. Additionally, a reed cap of animal horn is placed around the reed to contain the breath and allow circular breathing for constant play. In the Basque language, an alboka player is called albokari. The alboka is usually used to accompany a tambourine singer.

Alfaia

The alfaia is a Brazilian membranophone. It is a wooden drum made of animal skin tensioned or loosened through ropes placed alongside the body of the instrument. Alfaias are usually between 40 centimetres (16 in) and 55 centimetres (22 in) in diameter. Their construction is similar to 19th-century American and European military or field drums, and Latin American wooden bass drums. Their drumheads are clamped to the body through large wooden hoops, and they are played with distinctly-shaped thick wooden drum sticks. Sometimes the stick used in the dominant hand is marginally larger than the one used in the weak hand.

Algaita

The algaita (also spelled alghaita, algayta or algheita) is a double reed wind instrument from West Africa, especially among the Hausa and Kanuri peoples. Its construction is similar to the oboe-like rhaita and the zurna. The algaita is distinguished from these other instruments by its larger, trumpet-like bell. Instead of keys, it has open holes for fingering, similar to the zurna.

Alphorn

The alphorn or alpenhorn or alpine horn is a labrophone, consisting of a straight several-meter-long wooden natural horn of conical bore, with a wooden cup-shaped mouthpiece. Traditionally the Alphorn was made of one single piece, or two parts at most, and made from the wood of a red pine tree. Sometimes the trees would bend from the weight of snow during the wintertime, and this caused them to have the larger and bent mouthpiece at their ends. Modern Alphorns are sometimes made from three distinct parts that can be stuck together, this is to make them easier to transport via automobile, or even carried by hand, and today are more frequently made from the wood of a spruce tree or fir tree. It is used by mountain dwellers in the Swiss Alps. Similar wooden horns were used for communication in most mountainous regions of Europe, from the Alps to the Carpathians. Alphorns are today used as musical instruments.

Angklung

The angklung (Sundanese: ᮃᮀᮊᮣᮥᮀ) is a musical instrument from the Sundanese people in Indonesia made of a varying number of bamboo tubes attached to a bamboo frame. The tubes are carved to have a resonant pitch when struck and are tuned to octaves, similar to Western handbells. The base of the frame is held in one hand, while the other hand shakes the instrument, causing a repeating note to sound. Each performer in an angklung ensemble is typically responsible for just one pitch, sounding their individual angklung at the appropriate times to produce complete melodies (see Kotekan).

Appalachian dulcimer

The Appalachian dulcimer (many variant names; see below) is a fretted string instrument of the zither family, typically with three or four strings, originally played in the Appalachian region of the United States. The body extends the length of the fingerboard, and its fretting is generally diatonic.

Arpeggione

The arpeggione is a six-stringed musical instrument fretted and tuned like a guitar, but with a curved bridge so it can be bowed like a cello, and thus similar to the bass viola da gamba. The instrument is sometimes also called a guitar violoncello. The body shape of the arpeggione is, however, more similar to a medieval fiddle than either the guitar or the bass viol. It is essentially a bass viol with a guitar-type tuning, E–A–d–g–b–e' . The arpeggione is especially suited to playing runs in thirds, double stops, and arpeggios.

Ashiko

The ashiko is a drum, shaped like a tapered cylinder (or truncated cone) with the head on the wide end, and the narrow end open. It is made of hardwood and generally has a calfskin hide. Nowadays, goatskin is sometimes used, in imitation of the high sound of the popular djembe drum. It is played with the hands, and tuned by ropes. Ashiko drums – or variants thereof – are traditionally found in West Africa, as well as part of the Americas.

Atabaque

The atabaque (/ɑːtəˈbɑːkiː/; Brazilian Portuguese: [ataˈbaki]) is a tall, wooden, Afro-Brazilian hand drum. The shell is made traditionally of Jacaranda wood from Brazil. The head is traditionally made from calfskin. A system of ropes are intertwined around the body, connecting a metal ring near the base to the head. Because of this tuning mechanism the drum is sometimes known as 'Atabaque de Corda'. Wooden wedges are jammed between this ring and the body and a hammer is used to tighten or loosen the ropes, raising or lowering the pitch of the drum.

Autoharp

An autoharp or chord zither is a string instrument belonging to the zither family. It uses a series of bars individually configured to mute all strings other than those needed for the intended chord. The term autoharp was once a trademark of the Oscar Schmidt company, but has become a generic designation for all such instruments, regardless of manufacturer. The autoharp body is made of wood, and has a generally rectangular shape, with one corner cut off. The soundboard generally features a guitar-like sound-hole, and the top may be either solid wood or of laminated construction. A pin-block of multiple laminated layers of wood occupies the top and slanted edges, and serves as a bed for the tuning pins, which resemble those used in pianos and concert zithers.

Babendil

The babandil is a single, narrow-rimmed Philippine gong used primarily as the “timekeeper” of the Maguindanao kulintang ensemble. The babendil usually has a diameter of roughly one foot making it larger than the largest kulintang gong and comparable to the diameter of the agung or gandingan. However, unlike the gandingan or the agong, the babendil has a sunken boss which makes the boss relatively non-functional. Because of their sunken boss, babendils are instead struck either at the flange or the rim, using either bamboo betays or a strip of rattan, producing a sharp, distinctive metallic clang and are sometimes considered “false gongs.” In fact, this distinction makes the babendil classified as a bell in the Hornbostel-Sachs classification (if it were struck at the boss, it would be considered a gong.)

Bagpipes

Bagpipes are a woodwind instrument using enclosed reeds fed from a constant reservoir of air in the form of a bag. The Great Highland bagpipes are well known, but people have played bagpipes for centuries throughout large parts of Europe, Northern Africa, Western Asia, around the Persian Gulf and northern parts of South Asia. A set of bagpipes minimally consists of an air supply, a bag, a chanter, and usually at least one drone. Many bagpipes have more than one drone (and, sometimes, more than one chanter) in various combinations, held in place in stocks—sockets that fasten the various pipes to the bag.

Bajo sexto

Bajo sexto (Spanish: 'sixth bass') is a Mexican string instrument from the guitar family with 12 strings in six double courses. A closely related instrument is the bajo quinto (Spanish: 'fifth bass') which has 10 strings in five double courses. In playing, the left hand holds the strings against frets on a fingerboard, while the right hand plucks or strums the strings. When played in older styles of music where the instrument assumes the role of a bass, the strings are usually plucked with the fingers. In modern chordal and melodic styles, a pick is frequently used.

Bak

Bak (hangul: 박; hanja: 拍) is a wooden clapper used in Korean court and ritual music. The person playing the bak is called jipbak, serving as the conductor or musical supervisor for the group. The bak creates the clapping sound if clapped to indicate when the music starts. The upper part of the six long and narrow boards are tied with a string, and the lower part is held open with both hands, and then closed rapidly, creating a clear impact sound.

Balafon

The balafon is a gourd-resonated xylophone, a type of struck idiophone. It is closely associated with the neighbouring Mandé, Senoufo and Gur peoples of West Africa, particularly the Guinean branch of the Mandinka ethnic group, but is now found across West Africa from Guinea to Mali. Its common name, balafon, is likely a European coinage combining its Mandinka name ߓߟߊ bala with the word ߝߐ߲ fôn 'to speak' or the Greek root phono.

Balalaika

The balalaika (Russian: балала́йка, pronounced [bəɫɐˈɫajkə]) is a Russian stringed musical instrument with a characteristic triangular wooden, hollow body, fretted neck and three strings. Two strings are usually tuned to the same note and the third string is a perfect fourth higher. The higher-pitched balalaikas are used to play melodies and chords. The instrument generally has a short sustain, necessitating rapid strumming or plucking when it is used to play melodies. Balalaikas are often used for Russian folk music and dancing.

Bandola

The bandola is one of many varieties of small pear-shape chordophones found in Venezuela and Colombia. They are related to the bandurria and mandolin.

Bandolin

The bandolin is a 15-stringed musical instrument in Ecuador. It is used as a rhythm and melody instrument in the Andean region of Ecuador during festivals where dancing and music are involved. It has a flat back and 15 strings in triple courses. The body shape of the bandolin is similar to that of the bandola, the cuatro, or the guitar, with the caveat that, just as in the case of the mentioned instruments, luthiers who produce bandolins will incorporate into their personal designs changes to the body shape for a variety of reasons. It has 15 strings, in five courses of triple strings, in a guitar-tuning. It has a flat back, metal frets, and a slightly raised fingerboard in the front. The 15 strings run over a floating bridge to a metal tailpiece on the end of the body.

Bandoneon

The bandoneon (or bandonion, Spanish: bandoneón) is a type of concertina particularly popular in Argentina and Uruguay. It is a typical instrument in most tango ensembles. As with other members of the concertina family, the bandoneon is held between the hands, and by pulling and pushing actions force air through bellows and then routing air through particular reeds as by pressing the instrument's buttons. Bandoneons have a different sound from accordions, because bandoneons do not usually have the register switches that are common on accordions. Nevertheless, the tone of the bandoneon can be changed a great deal using varied bellows pressure and overblowing, thus creating potential for expressive playing and diverse timbres.

Banjo

The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, in modern forms usually made of plastic, originally of animal skin. Early forms of the instrument were fashioned by African Americans and had African antecedents. In the 19th century, interest in the instrument was spread across the United States and United Kingdom by traveling shows of the 19th century minstrel show fad, followed by mass-production and mail-order sales, including instruction method books. The inexpensive or home-made banjo remained part of rural folk culture, but 5-string and 4-string banjos also became popular for home parlour music entertainment, college music clubs, and early 20th century jazz bands. By the early 21st century, the banjo was most frequently associated with folk, bluegrass and country music, but was also used in some rock, pop and even hip-hop music. Among rock bands, the Eagles, Led Zeppelin, and the Grateful Dead, have used the five-string banjo in some of their songs.

Bansuri

A bansuri is an ancient side blown flute originating from the Indian subcontinent. It is an aerophone produced from bamboo and metal like material used in Hindustani classical music. It is referred to as nadi and tunava in the Rigveda and other Vedic texts of Hinduism. Its importance and operation is discussed in the Sanskrit text Natya Shastra.

Bara

The bara (Bambara: ߓߊ߬ߙߊ; also called bendré) is a spherical hand drum with a body made from a dried gourd or calabash, used in West Africa (primarily Burkina Faso, Côte d'Ivoire, and Mali). Its single head is made of goatskin. To make the drum, a dried gourd is cut on one end and a single head made of goatskin is stretched across the opening. Bara drums come in various sizes, some quite large. The instrument is often used to accompany the balafon.

Baritone horn

The baritone horn, or sometimes just called baritone, is a low-pitched brass instrument in the saxhorn family. It is a piston-valve brass instrument with a bore that is mostly conical (like the higher pitched flugelhorn and alto (tenor) horn) but it has a narrower bore compared to the similarly pitched euphonium. It uses a wide-rimmed cup mouthpiece like that of its peers, the trombone and euphonium. Like the trombone and the euphonium, the baritone horn can be considered either a transposing or non-transposing instrument. In the UK, the baritone horn is part of the standardised instrumentation of brass bands. In concert band music, there is often a part marked baritone, but these parts are most commonly intended for, and played on, the euphonium. A baritone can also play music written for a trombone due to similarities in timbre and range.

Barrel drum

Barrel drums are a class of membranophone, or drum, characterized by a barrel-shape with a bulge in the middle. They are often one-headed and open at the bottom. Examples include the Vietnamese trong chau and the bendre of the Mossi of Burkina Faso. Barrel drum is played horizontally.

Bass drum

The bass drum is a large drum that produces a note of low definite or indefinite pitch. The instrument is typically cylindrical, with the drum's diameter much greater than the drum's depth, with a struck head at both ends of the cylinder. The heads may be made of calfskin or plastic and there is normally a means of adjusting the tension either by threaded taps or by strings. Bass drums are built in a variety of sizes, but size does not dictate the volume produced by the drum. The pitch and the sound can vary much with different sizes, but the size is also chosen based on convenience and aesthetics. Bass drums are percussion instruments and vary in size and are used in several musical genres.

Bass guitar

The bass guitar, electric bass or simply bass (/beɪs/), is the lowest-pitched member of the guitar family. It is a plucked string instrument similar in appearance and construction to an electric or acoustic guitar, but with a longer neck and scale length, and typically four to six strings or courses. Since the mid-1950s, the bass guitar has largely replaced the double bass in popular music. The four-string bass guitar is usually tuned the same as the double bass, which corresponds to pitches one octave lower than the four lowest-pitched strings of a guitar (typically E, A, D, and G). It is played primarily with the fingers or thumb, or with a pick. To be heard at normal performance volumes, electric bass guitars require external amplification.

Bassoon

The bassoon is a woodwind instrument in the double reed family, which plays in the tenor and bass ranges. It is composed of six pieces, and is usually made of wood. It is known for its distinctive tone color, wide range, versatility, and virtuosity. It is a non-transposing instrument and typically its music is written in the bass and tenor clefs, and sometimes in the treble. There are two forms of modern bassoon: the Buffet (or French) and Heckel (or German) systems. It is typically played while sitting using a seat strap, but can be played while standing if the player has a harness to hold the instrument. Sound is produced by rolling both lips over the reed and blowing direct air pressure to cause the reed to vibrate. Its fingering system can be quite complex when compared to those of other instruments. Appearing in its modern form in the 19th century, the bassoon figures prominently in orchestral, concert band, and chamber music literature, and is occasionally heard in pop, rock, and jazz settings as well. One who plays a bassoon is called a bassoonist.

Batá drum

The Batá drum is a double-headed drum shaped like an hourglass with one end larger than the other. The percussion instrument is still used for its original purpose as it is one of the most important drums in the yoruba land and used for traditional and religious activities among the Yoruba. Batá drums have been used in the religion known as Santería in Cuba since the 1800s, and in Puerto Rico and the United States since the 1950s. Today, they are also used for semi-religious musical entertainment in Nigeria and in secular, popular music. The early function of the batá was as a drum of different gods, of royalty, of ancestors and a drum of politicians, impacting all spheres of life in Yoruba land.

Bawu

The bawu (simplified Chinese: 巴乌; traditional Chinese: 巴烏; pinyin: bāwū; also ba wu) is a Chinese wind instrument. Although shaped like a flute, it is actually a free reed instrument, with a single metal reed. It is played in a transverse (horizontal) manner. It has a pure, clarinet-like timbre and its playing technique incorporates the use of much ornamentation, particularly bending tones. The bawu likely originated in the Yunnan province of southwest China, it has become a standard instrument throughout China, used in modern Chinese compositions for traditional instrument ensembles. The instrument is also closely associated with Hmong, Yi, Hani and other minority cultures in southwestern China. It is typically used as a solo instrument, and is often featured in film scores; it is sometimes also heard in popular music recordings.
