Ambient music is a loosely defined musical genre that incorporates elements of a number of different styles - including jazz, electronic music, new age, rock and roll, modern classical music, reggae, traditional, world and even noise.
" Ambient Music must be able to accommodate many levels of listening attention without enforcing one in particular; it must be as ignorable as it is interesting. "
The earliest electronic soundscape music and theories come from the work of Pierre Schaeffer who followed the futurists in classifying music into categories such as man made, natural, short and long. He made some of the first electronic music using record players and natural sounds, and cutting up tape, making the first experimental music use of recording and magnetic tape. Even his work can be seen as preempted by Shopenhauer's ideas of 'soundworlds', literally worlds made up entirely of sounds. Karlheinz Stockhausen created pioneering electronic musical experiments later in 1955, and these two (amongst others) lay the groundwork for ambient music to appear decades later when music technology had developed.
The term ambient music was first coined by Brian Eno in the late 1970s to refer to music that would envelop the listener without drawing attention to itself, that can be either "actively listened to with attention or as easily ignored, depending on the choice of the listener" (Eno, who describes himself as a "non-musician" termed his experiments in sound as "treatments" rather than as traditional performances). Hence, Brian Eno is considered the father of ambient music: his 1978 release Ambient 1: Music for Airports includes a manifesto describing this music. Although having coined the word "ambient", he is also quick to reference the works and influence of Erik Satie. Eno coined the term in an essay to distance his work from elevator music and Muzak, it is more often similar to mood music or an ambient background in movie and radio sound effects. Often listeners will forget they are listening to ambient music, which is one of the biggest attractions of the genre. It can be any musical style, including jazz, electronic music and modern classical music.
Some of the works of the 20th century French composer Erik Satie, today best known for his Trois Gymnopédies suite, can be regarded as predecessors of modern ambient music. He referred to some of his music as "Musique d'ameublement" ('furniture music' ,or more literally, 'music for the furniture' and 'music to mingle with knives and forks', referring to something that could be played during dinner and would simply create an atmosphere for that activity rather than be the focus of attention. Similarly some of the works of the French composer Edgard Varèse, who used the theremin extensively in his compositions as well as atonal techniques and non-standard time signatures, can also be viewed as predecessors of ambient music. John Cage created the ultimate ambient work with his 4'33", three periods of silence first played on the piano, which make the audience listen to the ambient sound surrounding them. Cage inspired minimalist composers such as La Monte Young, Morton Feldman, Terry Riley, Steve Reich and Philip Glass also influenced Eno's groundbreaking style, and ambient music can be seen as a kind of minimalism.
Early albums from the 1960s & 1970s by Pink Floyd (such as A Saucerful of Secrets, Atom Heart Mother and Meddle), and by Tangerine Dream, (such as Alpha Centuri, Zeit & Phaedra (1971-1974)), have greatly influenced the genre. Probably the first electronic ambient albums were Affenstunde (1970) and In Den Garten Pharaos (1971) by Popol Vuh. Also, the album Sonic Seasonings (1972) by Wendy Carlos has been important. Other early artists such as Klaus Schulze - a former member of Tangerine Dream, Jean-Michel Jarre, Kraftwerk, and Vangelis in the 1970s and 1980s became important. Ray Lynch, Suzanne Ciani and Mannheim Steamroller in the mid-1980s created New Age music, selling millions independent from the mainstream music industry by direct order or new age shops.
After the Second Summer of Love in 1988 ambient music underwent a resurgence with the combination of rhythmic electronic dance music with the dreamy, meandering sound of Eno-style ambient music. Under the guise of various styles, ambient electronic music (sometimes referred to as ambient techno or ambient dub) saw the birth of a new wave of electronic music in the works of artists like The Orb, Aphex Twin, the Irresistible Force, and Geir Jenssen's Biosphere.
Ambient music evolved into forms of IDM, trance, synthpop and electronica. Early Warp records artists, (as well as later ones such as Aphex Twin), FSOL Future Sound of London (Lifeforms, ISDN) Autechre, (Incunabula, Amber), Boards of Canada, Massive Attack, Portishead and KLF all took a part in popularising and diversifying ambient music. There are now a dizzying array of different sub-genres, festivals, websites, discussion lists, clubs, labels and artists making new, interesting, original music.
Dark ambient music involves extensive use of digital reverb to create vast sonic spaces for frightening, bottom-heavy sounds such as deep drones, gloomy male chorus, echoing thunder, and distant artillery. It has a relentlessly gothic feel. Lustmord's collaboration with Robert Rich Stalker epitomizes this sub-genre.
Organic ambient music is characterised by integration of electronic, electric, and acoustic musical instruments. Aside from the usual electronic music influences, organic ambient tends to incorporate influences from world music, especially drone instruments and hand percussion. Organic ambient is intended to be more harmonious with nature than with the disco. Some of the artists in this sub-genre include Robert Rich, Steve Roach, Vidna Obmana, O Yuki Conjugate, James Johnson, Numina, and Tuu.
Some works by ambient pioneers such as Brian Eno, which use a combination of traditional (such as piano) and electronic instruments, would be considered organic ambient music in this sense. In the 70's and 80's Klaus Schulze often recorded string ensembles and performances by solo cellists to go along with his extended Moog synthesizer workouts.
Nature inspired ambient music
The music is composed from samples and recordings of naturally occurring sounds. Sometimes these samples can be treated to make them more instrument-like. The samples may be arranged in repetitive ways to form a conventional musical structure or may be random and unfocused. Sometimes the sound is mixed with urban or "found" sounds. Examples include much of Biosphere's Substrata, Mira Calix's insect music and Chris Watson's Weather Report. Some overlap occurs between organic ambient and nature inspired ambient. One of the first albums in the genre, Wendy Carlos' Sonic Seasonings, combines sampled and synthesized nature sounds with ambient melodies and drones for a particularly relaxing effect.
Isolationist ambient music is perhaps the darkest, most mysterious of ambient music. Inspired by industrial music, noise music, and classical music, isolationist may be too intense for the average listener. The Sombient label is the primary purveyor of isolationist ambient, in particular with the "drones" compilation series. Some of the artists known for this style of ambient music include Robert Fripp.
Other 'less ambient' ambient styles
There are many other styles which identify themselves as ambient music. There is information on these styles on other pages, but many artists who are not in the new age world of music making produce albums which mix beatless ambient music with downtempo electronica, so the categories have blured edges. Chill out (music) is generally linked to club culture and is sometimes used as a term which includes ambient music as a subset of itself. UK techno developed in particular at Warp Records in Sheffield, where previous electronic pioneers such as Cabaret Voltaire and Autechre laid the groundwork for ambient techno to develop, and for Aphex Twin and Boards of Canada to develop later. From this scene developed ambient dub and ambient techno. Intelligent Dance Music is another term synonymous with this scene. Electroacoustic and acousmatic music are 'classical' art music forms that use electronic sound creation instead of or alongside acoustic instruments. Glitch music is a subset of this work. Some club groups have made live ambient music, mixing dub techniques and styles with ambient textures and dance grooves, for example artists such as Sonic State, Junkielover, the Orb, Chillage People, H.U.V.A. Network, Solar Fields, The Starsound Orchestra and the Kuma Mela Project.
