Hi, What a wonderful opportunity. Here are a few (scatter brained?) ideas. Investigate tuned rear duplex and the variations (muted, detuned, etc.) Investigate alternate bridge termination technology. (three pins etc) Investigate increases in hammer mass using hammer shank weighting, so that the effect can be easily reversed. Investigate dramatic increase of mass at the hitch pin. Clamp on a twenty pound weight. Try a similar weight at the aggraffe. Try a similar weight on the tuning pins for a three string unison. Try a weight clamped to rear bridge pin, then front bridge pin and finally both. Investigate how sound envelope changes as a note is repeated at FF levels vs PP levels I.e envelope at strike #1 vs envelope at #100 vs envelope at #200 etc. Investigate how sound changes vs humidty changes. Do a test at 30% increasing by 5% per day until 60% RH is reached. Examine which way the unisons smear. Tune one unison approaching "from above pitch" and then repeat approaching "from below pitch". See how the spectrum changes with "pitch lock" technology applied to a unison. Vary the regulation parameters. Debed the key frame Have a wonderful time!
