  based on harmonic series[?] tune
  applied in dub-series[?]
  terms    ??

application of time series: if poss.
rather obvious to use: higher for values,
longer but time. Use perhaps spectral
methods including the version of this, &
also the taking of the mean as longest,
& the extreme pitches as shortest & v.v[?]

time series: sound of silence, decide optimum
range of sound, & for silence either: list these or
e.g. double these quantities etc. for silence - use
inverse, subtracted ratio, giving regular
rhythm, or use same sound lengths,
but made up to series quantities with
silence.  Adjust time scales to get different pace.

Simple time series, not based on pitch, but based
on time values in .|'s for each cluster.

Use counterpoint, of clusters in pitch series,
against clusters in simple series, timed
to begin & end simultaneously, at
different intensity levels & perhaps
in different 8ve.?
