Derek Bailey – microtonal motivic development in “Stella by Starlight”

Occurrences of minor-second cluster motive
Analysis of dissonances (in beats per second)
(f1-f2 = beating in beats per second) For example, if there were two pitches sounding together, 440Hz and 480Hz, they would create a beating at 40 beats per second (bps).
The following audio example consists of the 7 motivic occurrences in the recording of “Stella” next to a synthetic sine-wave representation of the resulting beating pattern with A400Hz as a reference point.
Furthermore, if we observe the synthetic representations without the original recording, the decreasing trajectory of the beating patterns becomes even more apparent.
