Loop (music) in the context of "CDJ"

In sound and music, sampling is the reuse of a portion (or sample) of a sound recording in another recording. Samples may comprise elements such as rhythm, melody, speech, or sound effects. A sample might comprise only a fragment of sound, or a longer portion of music, such as a drum beat or melody. Samples are often layered, equalized, sped up or slowed down, repitched, looped, or otherwise manipulated. They are usually integrated using electronic music instruments (samplers) or software such as digital audio workstations.

A process similar to sampling originated in the 1940s with musique concrète, experimental music created by splicing and looping tape. The mid-20th century saw the introduction of keyboard instruments that played sounds recorded on tape, such as the Mellotron. The term sampling was coined in the late 1970s by the creators of the Fairlight CMI, a synthesizer with the ability to record and playback short sounds. As technology improved, cheaper standalone samplers with more memory emerged, such as the E-mu Emulator, Akai S950 and Akai MPC.

A carousel or carrousel (mainly North American English), merry-go-round (International English), or galloper (British English) is a type of amusement ride consisting of a rotating circular platform with seats for riders. The seats are traditionally in the form of rows of animal figures (usually horses) mounted on posts, many of which move up and down to simulate galloping. Sometimes chair-like or bench-like seats are used, and occasionally mounts can take the form of non-animals, such as airplanes or cars. Carousel rides are typically accompanied by looped circus music.

The word carousel derives from the French word carrousel, meaning little battle, a reference to European tournaments of the same name starting in the 17th century. Participants in these tournaments rode live horses and competed in various cavalry skill tests, such as ring jousting. By the end of that century, simple machines were created in which wooden horses were suspended from a spinning wheel mounted on top of a central pole, allowing competitors to practice ring jousting without tiring their horses. These early contraptions soon became common with traveling fairs in Europe, and by the 19th century, their popularity spread to North America, where they became staple attractions in traveling carnivals and some of the first purpose-built amusement parks. Most historic carousel animal figures, including those made during the golden age of carousels from the 1870s to the early 1930s, were made from wood, and were carved and painted by hand. Hand-carved wood was replaced with more economic aluminum castings and later fiberglass castings in the 20th century. Many carousels operate around the world today and are often used to symbolize the entire amusement industry.

In music, tape loops are loops of magnetic tape used to create repetitive, rhythmic musical patterns or dense layers of sound when played on a tape recorder. Originating in the 1940s with the work of Pierre Schaeffer, they were used among contemporary composers of 1950s and 1960s, such as Éliane Radigue, Steve Reich, Terry Riley, and Karlheinz Stockhausen, who used them to create phase patterns, rhythms, textures, and timbres. Popular music authors of 1960s and 1970s, particularly in psychedelic, progressive and ambient genres, used tape loops to accompany their music with innovative sound effects. In the 1980s, analog audio and tape loops with it gave way to digital audio and application of computers to generate and process sound.

Philip Jeck (15 November 1952 – 25 March 2022) was an English composer and multimedia artist. His compositions were noted for utilising antique turntables and vinyl records, along with looping devices and both analogue and digital effects. Initially composing for installations and dance companies, beginning in 1995 he released music on the UK label Touch.
