Some other tuning possibilities would be lovely, though they are time- consuming, and probably not all are feasible. Most feasible: Unisons: find a few notes where it is possible to get "dead on" unisons both "by ear" and with ETD showing 0.0 (or essentially so - use more than one ETD). Get a reading. Then tune one string up 0.5 cents. Get a reading. Then tune a second string down 0.5 cents. Get a reading. Do this not only for the unison in isolation, but also played together with intervals, particularly octave, 12th, 5th, double octave, double octave fifth. And maybe in the context of chords. One reason is to investigate the "de-coupling" that seems to happen when a not good enough unison is played with an octave. Octaves: Different partial matches: 2:1, 4:2, 6:3, etc (higher numbers in bass notes). Same thing done with multiple octaves: stacked 2:1, 4:2, etc (Eg, play C2, C3, C4, C5 at the same time with each of those partial matches). Less feasible: Investigate tuning styles. For instance, a tuning based on 6:1 double octave fifths, compared to one based on 4:1 double octaves, compared to one based on 3:1 twelfths. Play large chords to get at overall resonance of the piano. Investigate alternate temperaments, same kind of testing. Regards, Fred Sturm fssturm at unm.edu http://www.youtube.com/fredsturm
