Hello Harmonic Entropy List. 5:16:21:25, ...another chord which, I
think, sounds interesting and unique, and which has an interesting
number feature. Among the chords I use, I haven't found any other 4
note chord, relatively high in the series, where every interval -- but
for the outer interval -- is already reduced. I believe this is a
result of the chord being only relatively high in the series (ie,
above 16), with the chord tones 21 and 25 being only 'first order',
and not multiples of those numbers, such as a chord whose harmonic
series numbers are in the forties or fifties or beyond). If height in
the series is a factor in dissonance, couldn't this be relavent?

Regards, Kelly
