Drone (music) in the context of "Organum"

An aulos (plural auloi; Ancient Greek: αὐλός : aulós, plural αὐλοί : auloí) or Latin: tibia was a wind instrument in ancient Greece, often depicted in art and also attested by archaeology.

Though the word aulos is often translated as "flute" or as "double flute", the instrument was usually double-reeded, and its sound—described as "penetrating, insisting and exciting"—was more akin to that of modern woodwind instruments such as oboes or bagpipes with a chanter and (modulated) drone.

Minimal music (also called minimalism) is a form of art music or other compositional practice that employs limited or minimal musical materials. Prominent features of minimalist music include repetitive patterns or pulses, steady drones, consonant harmony, and reiteration of musical phrases or smaller units. It may include features such as phase shifting, resulting in what is termed phase music, or process techniques that follow strict rules, usually described as process music. The approach is marked by a non-narrative, non-teleological, and non-representational approach, and calls attention to the activity of listening by focusing on the internal processes of the music.

The approach originated on the West Coast of the United States in the late 1950s and early 1960s, particularly around the Bay Area, where La Monte Young, Terry Riley and Steve Reich were studying and living at the time. After the three composers moved to the East Coast, their music became associated with the New York Downtown music scene of the mid-1960s, where it was initially viewed as a form of experimental music called the New York Hypnotic School. In the Western art music tradition, the American composers Moondog, La Monte Young, Terry Riley, Steve Reich and Philip Glass are credited with being among the first to develop compositional techniques that exploit a minimal approach. The movement originally involved dozens of composers, although only five (Young, Riley, Reich, Glass, and later John Adams) emerged to become publicly associated with American minimal music; other lesser known pioneers included Dennis Johnson, Terry Jennings, Richard Maxfield, Pauline Oliveros, Phill Niblock, and James Tenney. In Europe, the music of Louis Andriessen, Karel Goeyvaerts, Michael Nyman, Howard Skempton, Éliane Radigue, Gavin Bryars, Steve Martland, Peter Michael Hamel, Henryk Górecki, Arvo Pärt and John Tavener exhibits minimalist traits.

La Monte Thornton Young (born October 14, 1935) is an American composer, musician, and performance artist recognized as one of the first American minimalist composers and a central figure in post-war avant-garde music. He is best known for his exploration of sustained tones, beginning with his 1958 composition Trio for Strings. His compositions have called into question the nature and definition of music, most prominently in the text scores of his Compositions 1960. While few of his recordings remain in print, his work has inspired prominent musicians across various genres, including avant-garde, rock, and ambient music.

Young played jazz saxophone and studied composition in California during the 1950s, and subsequently moved to New York in 1960, where he was a central figure in the downtown music and Fluxus art scenes. He then became known for his pioneering work in drone music (originally called dream music) with his Theatre of Eternal Music collective, alongside collaborators such as Tony Conrad, John Cale, and his wife, the multimedia artist Marian Zazeela. In 1964, he began work on his unfinished improvisatory composition The Well-Tuned Piano, iterations of which he has performed throughout subsequent decades.

Bariolage is a musical technique used with bowed string instruments that involves rapidly playing alternated notes on adjacent strings, one of which is generally left open, thereby exploiting the different timbres of each string. Bariolage may involve quick alternation between a static note and changing notes that form a melody either above or below the static note. The static note is usually an open string note, which creates a highly resonant sound. In bluegrass fiddling the technique is known as "cross-fingering".

The term bariolage appears to have been coined in the nineteenth century to denote an eighteenth-century violin technique requiring flexibility in the wrist and forearm, the mechanics of which are not discussed by nineteenth-century writers. Etymologically, in French, the term was taken from the noun bariolage meaning a 'disorderly mix of bright colors', which in turn derives from the verb barioler meaning 'to cover with a mix of bright colors'. The bowing technique most often used for bariolage is called ondulé in French or ondeggiando In Italian. Bariolage may also be executed with separate bow strokes.

Drone music (also known as drone-based music, or simply drone) is a minimalist genre of music that emphasizes the use of sustained sounds, notes, or tone clusters called drones. It is typically characterized by lengthy compositions featuring relatively slight harmonic variations. La Monte Young, one of its 1960s originators, defined it in 2000 as "the sustained tone branch of minimalism." Music containing drones can be found in many regional traditions across Asia, Australia, and Europe, but the genre label is generally reserved for music originating with the Western classical tradition. Elements of drone music have been incorporated in diverse genres such as rock, ambient, and electronic music.

The Pamiri rubab (Russian and Tajiki: рубоб) is a fretless six-strung lute, carved from a single piece of wood with a skin head. It is played in the Badakhshan region of Tajikistan, as part of the Pamiri musical tradition.

The Pamiri rubab has six gut strings or nylon strings, one of which, rather than running from the head to the bridge, is attached partway down the neck, similar to the fifth string of the American banjo. The instrument is primarily used for drone and rhythm accompaniment, for instance accompanying spoken or sung poetry. The rubab is played for the way it sounds, the gut strings emitting a "less strident sound" than that produced by a metal strung instrument.

The kissar (also spelled kissir), tanbour or gytarah barbaryeh is the traditional Nubian lyre, still in use in Egypt, Sudan, Eritrea and Ethiopia. It consists of a body having instead of the traditional tortoise-shell back, a shallow, round bowl of wood, covered with a soundboard of sheepskin, in which are two small round sound-holes. The arms, set through the soundboard at points distant about the third of the diameter from the circumference, have the familiar fan shape. Five gut strings, knotted round the bar and raised from the soundboard by means of a bridge tailpiece similar to that in use on the modern guitar, are plucked by means of a plectrum by the right hand for the melody, while the left hand sometimes twangs some of the strings as a soft drone accompaniment.

The kissar has been a popular instrument in northern Sudan in Nubian and Shaigiya music, but also among the Nuba and Beja people.
