Music loop

In electronic music, a loop is a sample which is repeated. Loops may be repeated through the use of tape loops, delay effects, cutting between two record players, sampling, a sampler or with the aid of Computer Based Looping Software.

Definitions

"Loops are short sections of tracks (probably between one and four bars in length), which you believe might work being repeated." A loop is not "any sample, but...specifically a small section of sound that's repeated continuously." Contrast with a one-shot sample. (Duffell 2005, p.14)

"A loop is a sample of a performance that has been edited to repeat seamlessly when the audio file is played end to end." (Hawkins 2004, p. 10)

Origins

While repetition is used in the musics of all cultures the first musicians to use loops were electronic pioneers Pierre Henry, Edgard Varèse and Karlheinz Stockhausen. Stockhausen's music in turn influenced the Beatles to experiment with tape loops, and their use of loops in early psychedelic works (most notably 1966's "Tomorrow Never Knows" and 1968's avant-garde "Revolution 9") brought the technique into the mainstream. Later, inspired by Terry Riley's use of one tape on two tape machines, Brian Eno and Robert Fripp created the technical basis for their (No Pussyfooting) album - this technological concept was later dubbed Frippertronics.

Another approach was the use of pre-recorded loops, first exemplified by Grandmaster Flash and his turntablism.

Use of pre-recorded loops made its way into many styles of popular music, including hip hop, trip hop, techno, drum and bass, and contemporary dub, as well as into mood music on soundtracks.

Modern looping

Today many musicians use digital hardware and software devices to create and modify loops, often in conjunction with various electronic musical effects.

In the early 1990's dedicated digital devices were invented specifically for the use in live looping i.e. loops that are recorded in front of a live audience. Live looping is not exclusive to electronic music and is found in the singer/songwriter genre, achieving new popularity in the employ of popular artists such as Ani DiFranco and KT Tunstall.

Computer programs to create music using loops range in features, user friendliness, and price. Some of the most widely used are, Digidesign's Pro Tools, Sony's ACID, Cakewalk Sonar, ReCycle, GarageBand, FL Studio (formerly Fruity Loops), Propellerhead's Reason and Ableton Live.

In 2004 there were 20 live looping festivals in 12 countries in this burgeoning international movement. These include Loopstock established in 2002 in the San Luis Obispo, California, and the Y2K? series, established in 2000 in Santa Cruz, California. The Y2K4 International Live Looping Festival in October 2004 in San Francisco and Santa Cruz drew 50 loopers from 5 different countries over four days.

The musical loop is one of the most important features of video game music. It is also the guiding principle behind devices like the Buddha machine, an ambient-music generating device.
