Joy - a composition for three or more voices or instruments

摘要

A musical study of time stretching. The final four bars of J.S. Bach's "Jesu, Joy of Man's Desiring" are subjected to a process of time stretching. In filmmaking, a common technique used to slow down a section of film is to duplicate each frame several times. Joy uses a similar approach, but with overlapping "frames" of three quavers: the first three quavers are repeated, followed by repetitions of quavers two to four, and so on, moving through the material a quaver at a time. The result is a seamless expansion of the time frame of the original source.
