Drone music is a minimalist musical style that emphasizes the use of sustained or repeated sounds, notes, or tone-clusters – called drones. It is typically characterized by lengthy audio programs with relatively slight harmonic variations throughout each piece compared to other musics. La Monte Young, one of its 1960s originators, defined it in 2000 as "the sustained tone branch of minimalism".
Explorers of drone music since the 1960s have included Theater of Eternal Music (aka The Dream Syndicate: La Monte Young, Marian Zazeela, Tony Conrad, Angus Maclise, John Cale, et al.), Charlemagne Palestine, Eliane Radigue, Philip Glass, Kraftwerk, Klaus Schulze, Tangerine Dream, Melvins, Sonic Youth, Band of Susans, The Velvet Underground, The Godz, Robert Fripp & Brian Eno, My Bloody Valentine, Steven Wilson, Ghola, Phil Manzanera, Phill Niblock, Michael Waller, David First, Kyle Bobby Dunn, Robert Rich, Steve Roach, Earth, Rhys Chatham, Coil, If Thousands, John Cage, Labradford, Lawrence Chandler, Stars of the Lid, Sonic Boom, Sheila Chandra, Hwyl Nofio, Janek Schaefer, This Will Destroy You, Electric Wizard, Tim Hecker, Basilisk, Locrian, Nu//, and Sunn O))).
Ethnic or spiritual music which contains drones and is rhythmically still or very slow, called "drone music", can be found in many parts of the world, including bagpipe traditions, among them Scottish pibroch piping; didgeridoo music in Australia, South Indian classical Carnatic music and Hindustani classical music (both of which are accompanied almost invariably by the tambura, a plucked, four-string instrument which is only capable of playing a drone); the sustained tones found in the Japanese gagaku classical tradition; possibly (disputed) in pre-polyphonic organum vocal music of late medieval Europe; and the Byzantine chant's ison (or drone-singing, attested after the fifteenth century). Repetition of tones, supposed to be in imitation of bagpipes, is found in a wide variety of genres and musical forms. However, the lineage of stillness and long tones occurring in classical compositions during adagio movements, including, for instance, the third movement of Anton Webern's Five Small Pieces for Orchestra, as well as in Northern European folk musics in the form of "slow airs" has directly descended into modern popular and electronic music.
The modern genre also called drone music (called "dronology" by some books, labels and stores, to differentiate it from ethnic drone-based music) is often applied to artists who have allied themselves closely with underground music and the post-rock or experimental music genres. Drone music also fits into the genres of found sound, minimalist music, dark ambient, drone doom/drone metal, and noise music. Most often utilizing electronic instruments or electronic processing of acoustic instruments, they typically create dense and unmoving harmonies and a stilled or "hovering" sense of time. While the hallmarks of drone music are easy to recognize, the backgrounds and goals of the artists vary greatly.
Pitchfork Media and Allmusic journalist Mark Richardson defined it thus: "The vanishing-point music created by drone elders Phill Niblock and, especially, LaMonte Young is what happens when a fixation on held tones reaches a tipping point. Timbre is reduced to either a single clear instrument or a sine wave, silence disappears completely, and the base-level interaction between small clusters of "pure" tone becomes the music's content. This kind of work takes what typically helps us to distinguish "music" from "sound," discards nearly all of it, and then starts over again from scratch."
As summarized in a review, "Drone music is about as far away from music as you can get before it stops being music [...] In the beginning, there was the word, and the word was oooooommmmmmm. God was, apparently, a drone music pioneer, and there is something religious about this music... or rather, something spiritual."
La Monte Young and the Theater of Eternal Music
La Monte Young, fascinated with "the sound of the wind blowing", the "60 cycle per second drone" of "step-down transformers on telephone poles", the tanpura drone and the alap of Indian classical music, "certain static aspects of serialism, as in the Webern slow movement of the Symphony Opus 21", and Japanese gagaku "which has sustained tones in it in the instruments such as the Sho", started writing music incorporating sustained tones in 1957 with the middle section of Four Brass, then in 1958 what he describes as "the first work in the history of music that is completely composed of long sustained tones and silences" with Trio for Strings, before exploring this drone music within the Theater of Eternal Music that he founded in 1962.
The Theater of Eternal Music is a multi-media performance group who, in its 1960s–1970s heyday included at various times La Monte Young, Marian Zazeela, Tony Conrad, Angus MacLise, Terry Jennings, John Cale, Billy Name, Jon Hassell, Alex Dea and others, each from various backgrounds (classical composition and performance, painting, mathematics, poetry, jazz, etc.). Operating from the world of lofts and galleries in New York in the mid-sixties to the mid-seventies in particular, and tied to the aesthetics of Fluxus and the post-John Cage-continuum, the group gave performances on the East Coast of the United States as well as in Western Europe comprised long periods of sensory inundation with combinations of harmonic relationships, which moved slowly from one to the next by means of "laws" laid out by Young regarding "allowable" sequencies and simultaneities, perhaps in imitation of Hindustani classical music which he, Zazeela and the others either studied or at least admired. The group released nothing during their lifetime (although Young and Zazeela issued a collaborative LP in 1969, and Young contributed in 1970 one side of a flexi-disc accompanying Aspen magazine). The concerts themselves were influential on their own upon the art world including Karlheinz Stockhausen (whose Stimmung bears their influence most strikingly) and the drone-based minimalist works of dozens of other composers many of whom made parallel innovations including Young classmate Pauline Oliveros, or Eliane Radigue, Charlemagne Palestine, Yoshi Wada, Phill Niblock and many others. Then group member John Cale went on to extend and popularize this work into 1960s rock music with the Velvet Underground (along with songwriter Lou Reed).
In 2000, La Monte Young wrote: "[About] the style of music that I originated, I believe that the sustained tone branch of minimalism, also known as “drone music,” is a fertile area for exploration."
John Cale and the Velvet Underground
The Velvet Underground's first EP release in 1966, entitled Loop was an experimental drone piece created by member John Cale. This rare release was far removed from the band's usual rock-based music, however the usage of drone elements in these songs was still apparent, particularly in the song "Heroin", which consisted of Cale's grinding viola drone with Reed's two-chord guitar figure. This song, appearing on the band's first album The Velvet Underground & Nico (1967), laid the foundation for drone music as a rock music genre in close proximity to the art-world project of the Theatre of Eternal Music. Cale's departure from the group in 1968 blurred matters considerably, as Reed continued to play primitive figures (sometimes in reference to R&B), while Cale went quickly on to produce the Stooges' debut (1969), including his viola drone on the track "We Will Fall" and Nico's The Marble Index (1969) which also included Cale's viola drone on "Frozen Warnings". Later, Lou Reed issued in 1975 a double LP of multi-tracked electric-guitar feedback titled Metal Machine Music which listed (misspelling included) "Drone cognizance and harmonic possibilities vis a vis Lamont Young's Dream Music" among its "Specifications".
In the late sixties and early seventies German rock musicians including Can, Neu! and Faust drew from the heritage of experimental sixties rock like Captain Beefheart at his most collagic and jamming as well as from composers like Stockhausen and La Monte Young. These groups became influential on art-rock contemporaries in their own day and punk-rock and post-punk players subsequently. Tony Conrad, of the Theater of Eternal Music, notably made a collaborative LP with Faust which included nothing but two sides of complex violin drones accompanied only by a single note on bass guitar and a bloody-minded percussion accompaniment. Single-note bass-lines were also featured on Can's track "Mother Sky" (album Soundtracks, 1970) and the entirety of Die Krupp's first album (1979).
New age, cosmic and ambient music
Parallel to Krautrock's rockist impulses, across North America and Europe, some musicians sought to reconcile Asian classicalism, austere minimalism and folk music's consonant aspects in the service of spiritualism. Among them was Theater of Eternal Music alumnus Terry Riley with his 1964 In C  and who had become a disciple, along with Young and Zazeela, of the Hindustani classical singer Pandit Pran Nath. In parallel, then-Krautrock band Tangerine Dream and their recently departed member Klaus Schulze both moved toward a more contemplative and consonant harmonic music, each releasing their own drone music album on the label Ohr in August 1972 (Zeit and Irrlicht, respectively). Meanwhile, as increasingly elaborate studio technology was born during the seventies, Brian Eno, an alumn of the glam/art-rock band Roxy Music postulated ambient music (drawing, in part from John Cage and his antecedent Erik Satie's 1910s concept of furniture music, in part from minimalists such as La Monte Young) as "able to accommodate many levels of listening attention without enforcing one in particular; it must be as ignorable as it is interesting". While his late seventies ambient tape-music recordings are not drone music, his acknowledgment of Young ("the daddy of us all") and his influence on later drone music made him an undeniable link in the chain. Klaus Wiese have been a master of the Tibetan singing bowls, he created an extensive series of album releases using them, making impressive acoustic drones.

Bowery Electric, Cocteau Twins, Coil, My Bloody Valentine, Slowdive, The Jesus and Mary Chain, Ride, Loop (who covered Can's "Mother Sky"), Brian Jonestown Massacre (Methodrone album) and Spacemen 3 (who used a text by Young for the liner notes to their record Dreamweapon: An Evening of Contemporary Sitar Music, a live 45-minute drone piece) reasserted the influence of the Velvet Underground and its antecedents in their use of overwhelming volume and hovering sounds, while Sonic Youth quite often prolong notes to add more droning in their songs.
Electronics and metal
In the late 1990s and early 2000s, drone music was intermixed with rock, ambient, dark ambient, electronic and new-age music. Many drone music originators, including Phill Niblock, Eliane Radigue and La Monte Young are still active and continue to work exclusively in long, sustained tones. Improvisors like Hototogisu and Sunroof! play nothing but sustained fields which are close to drones. Sunn O))), a drone metal band, almost exclusively plays sustained tone pieces, and their peers Merzbow and Boris released a collaborative 62-minute drone piece called Sun Baked Snow Cave in 2005. At times colloquialized as droan, this post-metal genre continues with many contemporary projects, such as Gygax on 12th Records.

- From experimental music, not ambient music: Although drone is now seen as a subgenre of both Minimalism and Ambient, Ambient came in part from Drone, not the other way around (cf. below citations of Cook & Pople 2004, p. 502, and ambient founder Eno's quote about Young)
- Cox & Warner 2004, p. 301 (in "Thankless Attempts at a Definition of Minimalism" by Kyle Gann): "Certainly many of the most famous minimalist pieces relied on a motoric 8th-note beat, although there were also several composers like Young and Niblock interested in drones with no beat at all. [...] Perhaps “steady-beat-minimalism” is a criterion that could divide the minimalist repertoire into two mutually exclusive bodies of music, pulse-based music versus drone-based music."
- Cox & Warner 2004, p. 359 (in "Post-Rock" by Simon Reynolds): "The Velvets melded folkadelic songcraft with a wall-of-noise aesthetic that was half Phil Spector, half La Monte Young—and thereby invented dronology, a term that loosely describes 50 per cent of today's post-rock activity." (about the Velvet Underground and post-rock)
- Young 2000, p. 27
- Early use of "drone music" as an ethnic or spiritual, drone-based music can be found such as in 1958 (American Musicological Society, JAMS (Journal of the American Musicological Society), 1958, p. 255: "Remarks such as those on drone effects produced by double pipes with an unequal number of holes provoke thoughts about the mystery of drone music in antiquity and about primitive polyphony.") or 1972 (Barry S. Brook & al., Perspectives in Musicology, W. W. Norton, 1972, ISBN 0-393-02142-4, p. 85: "My third example of the force of tradition concerns another large problem, the persistence of drone music from the Middle Ages to the present day.")
- Early use of "drone music" as a non-ethnic, new or experimental genre can be found such as in 1974 (Michael Nyman, Experimental Music: Cage and Beyond, Studio Vista, 1974, ISBN 0-02-871200-5, p. 20: "[...] LaMonte Young's drone music [...]") or again 1974 (cf.

- "Drone ambient" is used for instance on Allmusic, such as in the review of Soundtrack for the Aquarium ("representative of the drone ambient side of his work").
- "Ambient drone" is used for instance on Allmusic (and thus mirrored on VH1, Amazon, etc.), such as in the biography of Stars of the Lid ("Ambient drone duo Stars of the Lid") or de:Mathias Grassow ("widely recognized as 'the King of the Ambient Drone' ") or on PopMatters ("experimental no-man’s-lands like ambient drone", "seminal works of ambient drone").
- "Dronescape" is used for instance on Allmusic, such as in the review of New York Noise, Vol. 2 ("one of Sonic Youth's first known recordings, the dronescape 'I Dreamed I Dream,' ")
- The independent record store Aquarius Records, in this catalog page (Archive.org copy of 2002), claims: "Here at Aquarius, we've coined such neologisms as "dronology" and "fuckery", simply because we hope that such words offer enough connotation even without a lot of context."

They are also of considerable antiquity, being known to the ancient Egyptians. [...] There are three characteristics of Bagpipe imitations all three of which may be present at the same time and any one of which is sufficient to characterize Bagpipe influence, if not a direct imitation. The first is the drone, usually placed in the bass, and consisting of one note alone or of two or three notes played together. A drone consisting of two adjacent notes sounded alternately is also typical. Dr. Naylor, in his work An Elizabethan Virginal Book, has drawn attention to the fact that many early English melodies are founded on a drone consisting of two alternating notes, and that the Northumbrian Bagpipe had alternative drones and an arrangement for changing the note of the drones."

He requested tapes of the group's performances which, perhaps surprisingly, Young gave him. Stockhausen's own musicians visited Young and Zazeela's Dream House installation in Antwerp in 1969."

I only realized later that this was Stockhausen's “Feldman piece” just as Stimmung was his “LaMonte Young piece”."

- Cox & Warner 2004, p. 320 (in "Digital Discipline: Minimalism in House and Techno" by Philip Sherburne): "In the late 1970s, rock music produced its own minimalist reaction to inflated, overproduced mainstream rock. The results, No Wave and punk rock, often made explicit links to the 60s' drone-minimalism tradition, as with Glenn Branca's bands Theoretical Girls and The Static, his guitar orchestras, and the many groups that he influenced."

- "Glass's discovery, during a 1969 runthrough of Music In Similar Motion, that sustained overtones and undertones were following the patterns played by the ensemble like an aural shadow. [...] And so, in his next piece, Music With Changing Parts, Glass decided to augment what was already occurring naturally. Toward the end of this new composition, he added in long tones, allotted to wind instruments and voices, held for the length of a breath, to support the notes that emerged from the keyboard patterns, with the rule that a player could reinforce any tone emerging from the whirl."

- "It's quite possibly some of Obmana's best work and it's representative of the drone ambient side of his work." (Matt Borghi review from AllMusic).
- "Vidna Obmana's penchant for getting interstellar mileage out of even the most minimal electronic drones. [...] Roach's acoustic and synthetic rhythms are in deliberate absence here, but as dark, electronic buds blossom and begin to seed the lifeless surroundings, the drones that erupt out of them vibrate with a tangible, malevolent pulse." (Darren Bergstein review from i/e). "This occurs through the composers' use of nebulous drones, and gorgeous passages of pure sonics drift" (Thom Jurek review from Detroit Metro Times).
- " 'Twenty-Three,' for massed violins, violas, and celli [...] is a gorgeous lattice of densely layered drones occupying a very small note range but varying widely in intensity of attack. Tony Conrad's violin music inevitably comes to mind, [...]" (review at AllMusic).
