Trichords tuning

[Don]

Hi Roger,

Which Octave? What tuning style (OTS? Which way is right? (bass or treble)
Did you tune the bass string then middle then treble? or M B T or T M B?
Did you use the listener ear or just watch the spinner? What partials was
RCT listening to?

Interesting that your piano showed a *rise* in pitch. The ones I have
checked (small pso's) showed a drop in pitch with all three strings sounding.
