Just for fun I thought I'd re-send these two graphs, along with a third I made holding 3:1 pure In order -the actual harmonic series of the sampled piano in that long ago issue of the journal -the resulting octave types spread chromatically of that piano taken from C3/C4 to C4/C5 (4:2 octave type was held to 0.5 bps wide) -the resulting octave types spread chromatically when the 3:1 12th on another piano was held pure And as long as we're providing sound samples. Here is a fairly early version of my own P-12th. The recording was done in the spring of 2003. http://home.broadpark.no/~rbrekne/sounds/G.Tveitt15.mp3 G.
