Wendy Carlos (born Walter Carlos, November 14, 1939) is an American composer and electronic musician. She gained fame by playing others' music on synthesizers. Though her early albums were interpretations of the works of classical composers, she later released original compositions.
1972's Sonic Seasonings was packaged as a double album, with one side dedicated to each of the four seasons, and each side consisting of one long track. It blended recorded sounds with synthesized sounds, without melodies, to create an ambient effect. Not as popular as some other albums, it was however very influential on other artists who went on to create the ambient genre. Also in 1971, Carlos composed and recorded music for the soundtrack of the film A Clockwork Orange. She worked with Stanley Kubrick again on the score for The Shining, although in the end, Kubrick used mostly pre-existing music cues from other composers.
In 1982, she scored the theatrical film Tron for Disney. This score incorporated orchestra, chorus, organ, and both analog and digital synthesizers. Some of her end title music was replaced with a song by the rock group, Journey, and the music that originally was composed for the lightcycle scene was dropped. 1984's Digital Moonscapes switched to digital synthesizers, instead of the analog synthesizers that were the trademark of her earlier albums. Some of the unused material from the Tron soundtrack was incorporated into it.
1986's Beauty In the Beast saw Carlos experimenting with various alternate tunings, including just intonation, Balinese scales and several scales she invented for the album. One of her scales involved setting a "root note", and retuning all of the notes on the keyboard to just intonation intervals. There are a total of 144 possible notes per octave, from 12 notes in a chromatic scale times 12 different home keys. Other scales included Carlos' Alpha & Beta scales, which experimented with dividing the octave into a non-integer number of equally-spaced intervals.
1987's Secrets of Synthesis is a lecture by Carlos, with audio examples (many from her own recordings), expounding on topics she feels to be of importance. Some of the material is an introduction to synthesis, and some (e.g., a discussion of hocketing) is aimed at experienced musicians.
Beginning in 1998, all of her catalogue was remastered. In 2005, the two-volume set Rediscovering Lost Scores was released, featuring previously out-of-print material, including the unreleased soundtrack to Woundings, and music composed and recorded for The Shining, Tron and A Clockwork Orange that was not used in the films.
Her first six recordings were released under the name Walter Carlos. In 1972, Carlos underwent sex reassignment surgery. The last release to be credited to 'Walter' Carlos was By Request (1975). The first release credited to her as Wendy Carlos was Switched-On Brandenburgs (1979). Carlos's first public appearance after her gender transition was in an interview in the May 1979 issue of Playboy magazine, a decision she would come to regret because of the unwelcome publicity it brought to her personal life. On her official site, her transition is discussed in an essay stating that she values her privacy on the subject.
In 1998, Carlos sued the songwriter/artist Momus for $22 million for his satirical song "Walter Carlos" (which appeared on the album The Little Red Songbook), which suggested that if Wendy could go back in time she could marry Walter. The case was settled out of court, with Momus agreeing to remove it from the CD and owing $30,000 in legal fees.
Carlos is also an accomplished solar eclipse photographer.
