Balinese gamelan musicians are able to play with great speed because they are , a technique where two musicians interlock and share in creating the melody.

Explanation:  This is a style of playing characteristic of Balinese gamelan music, used for playing at high speed, which is possible because the notes are split between two instruments, i.e between two musicians. In this way, parts of the music that are locked together (interlocked), in the aforementioned manner are quickly played, separating the notes. The two separate parts played on the two instruments are thus combined to form a single musical line that is heard as a whole, that is, as an inseparable part, though it consists of two parts. Given that the notes have been previously split into two instruments, then the way of playing is locked again in its entirety, fast playing is possible. One note core, that is, a separable note, can be divided into two, four, and even eight notes, which are merged again into a single note core by combining the playing of multiple instruments in the aforementioned interlocking method.
