[39.4] TONE CLOCK IN JAZZ AND IMPROVISED MUSIC

Theo Hoogstins writes: "When Schönberg introduced the twelve tone system, based on the chromatic scale, the diatonic harmony system was not relevant anymore. Composers throughout the whole century have been looking for a solution to this problem, and it was Peter Schat who came up with an inventory of possible triads in the chromatic scale, which he concieved to connect to the time points or time markers of the clock, thus giving a possibility of reference and comunication to ideas of tonality in the chromatic scale."
