  • 1.  Pitch correction overshoots for pianofortes

    Greetings,

    I recently spent several days servicing a McNulty copy of a Conrad Graff piano in concert. for the first tuning that I put on this Instrument on each occasion, I did what I normally do with harps accords, which is to simply repeatedly tune it to pitch, with no overshoot.

    Since fortepianos seem to fall somewhere between harpsichords and modern Pianos, I wonder if anyone had any advice born of experience about whether or not it is safe to overshoot a ianoforte as one would do with a modern piano, whether it should be done to a lesser degree, or not at all.

    Ken Walkup at Cornell should be able to report from experience maintaining Malcolm Bilson's collection of pianos.

    I'd just ask McNulty directly! He's on FB Messenger, or I'm sure phone and email work just fine too.  My guess is that different pianos will all have different tolerances as far as how much overpull they'll like, given how much these varied...  They're really nice people.

    If one uses the old fashioned overpull method no damage will happen.

    If aiming for a 440 outcome tune all octaves of A C# F to 444, all octaves of B D# G to 443, G# C E to 442 and A# D F# to 441. The whole is likely to come out quite well at 440. If flatter than 440, then do standard tunings at 441 until 440 becomes the resulting norm.

    Best wishes

    Thanks for the suggestion of this approach, David. I haven't treid that before and since you have far more experience with early pianos than I do, I will give it a try.

    Ed and Nathan,

    I have reached out to Walkup and McNulty as you have respectively recommended.

    Thanks for the nudge!

    Alan
