First of all, is this on a = piano which you have determined only needs a one-pass tuning? In that = case I would recommend doing test blows on each note before you make up = your mind.=20 My preferred technique ( Not patented, no royalties, etc.) is to = give the piano two passes; every time. It's so easy to get it close on = the first pass, and then to be just nudging pins on the second pass, = knowing that the piano is already stabilized on the first pass. But the real reason I'm writing this is to note something that I = have noticed lately. Say I pitch raise a piano, five cents or so, and = when I'm done perhaps the piano, because of a stiff board-thick plate = combination (either one or both) the piano ends up a couple cents sharp. = I bang away while settling the pin, to get it back in tune, only to find = later that it's creeped up in pitch again.=20 I HATE IT WHEN THAT HAPPENS! =20 What I think is happening, is that you can pound a note too = hard. The blow from the hammer draws tension into the speaking length, = and later the string equalizes in the waste end, drawing the pitch = sharp.=20 =20 It's good to give a piano those test blows, nobody wants all those = call-backs from notes that go out. Different pianos respond differently, = we get used to them with experience. But I've always been a firm = believer in hard blows, and now I'm thinking maybe you can go too far. I remember Jim Coleman Sr. commenting on this phenomena, and sure = enough, now I'm starting to hear it. ----- Original Message -----=20 From: SimsPiano@AOL.COM=20 To: pianotech@ptg.org=20 Sent: Monday, February 25, 2002 11:48 AM Subject: Test Blows Hi, I've been taught to do a hard test blow on each string as I tune. = I've been=20 wondering if the following might be a more efficient way to tune using = a test=20 blow. 1) Tune the entire piano using no hard test blows, but working the = hammer=20 back and forth to try to take all torque out of the pin once the pitch = is=20 right. 2) After the whole thing is tuned, go back and give each key a few = hard test=20 blows. 3) Now touch up whatever went out. What I figured was that on trichords and bichords, you're only hitting = one=20 test blow per 2 or 3 strings instead of 1 per string, which means = either 2 or=20 3 times fewer test blows. By the way, I use a SAT and start A0 and go up the keyboard. Comments?? Thanks, Corey ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
