To Dale, David, Joe and Ron et al, I am trying to understand what determinations are considered when deciding on making a scale to include trichords or bichords? WHen you (all the piano re-designers out there) describe one scale as having better tone than the other, or you will sometimes favor tri-chords over bi-chords, what are talking about? Fundamental volume over higher overtones, less inharmonicity, lower break %? What is meant by "sounds" better? One piano you just "felt" like installing 3-string unisons on one piano that particular day and 2-string unisons the next day? I understand that ultimately one decision must be made in order to finish the job, but how does one make these determinations? You don't have to answer, but I am just very curious. Joe Wiencek
