Burkhard Hello Frank. Can you expand the area for the chamber tone a little? I had a piano today that should be tuned to A4=380Hz.
Lutz Hello Burkhard, perhaps a quick solution: choose the lowest concert pitch and tune every note a certain cent-amount lower, at 100 cent you can reach an additional semitone.
Frank Illenberger Hello Burkhard, sure, I can extend the range for the concert pitch. From your experience: What are the lowest and highest values you usually encounter?
Burkhard Hello Frank, I’ve never had any deeper than this 380Hz. Who knows what else you could use it for? +- 300 cents (?)
