If A4 is 8 beats flat, that means it is vibrating at 432 cycles instead of 440, which is 31.8 cents flat. If C4 is 8 beats flat, that means it is vibrating at 253.63 cycles instead of 261.63, which is 53.73 cents flat. If A4 is 8 cents flat, that means it is vibrating at 437.97 cycles instead of 440, creating about 2 beats per second. If C4 is 8 cents flat, that means it is vibrating at 260.42 cycles instead of 261.63, creating about 1.2 beats per second. There is no across-the-board equality between beats and cents. ----- Original Message ----- From: "Joseph Garrett" <joegarrett@earthlink.net> To: <pianotech@ptg.org> Sent: Monday, March 15, 2004 9:38 AM Subject: Beats vs cycles vs cents > One of our newer techs, just posted a query regarding pianos being flat in > an institutional situation.
