---------------------- multipart/alternative attachment Thanks Stephen, That's why I wrote to the list, I want to attend convention classes, not do math :-) Nice to have the number to 100 decimal places though, maybe I can really impress somebody! Diane Stephen Airy <stephen_airy@yahoo.com> wrote: Here's a method to figure it out, not accounting for inharmonicity. Since A4 is 440 Hz, an octave lower is 1/2 the frequency, or 220 Hz. A0 is the lowest note on the piano, being 27.5Hz. Multiply 27.5 by the 12th root of 2 (1.0594630943593 on my TI-92 Plus), and multiply each result by 1.0594630943593 88 more times. For example: 27.5 (A0) 27.5 * 1.0594630943593 = 29.135235094881 (A#0) 29.135235094881 * 1.0594630943593 = 30.867706328508 (B0) 30.867706328508 * 1.0594630943593 = 32.703195662575 (C1) continue the same pattern "up the scale" until you get to.... . . . . 3520 (A7) (may be a little bit off at the 12th digit to the right of the decimal point or something like that -- it often is on my calc) 3520 * 1.0594630943593 = 3729.3100921447 (A#7) 3729.3100921447 * 1.0594630943593 = 3951.066410049 (B7) 3951.066410049 * 1.0594630943593 = 4186.0090448096 (C8) You probably won't need all 12 or so digits. I recommend truncating the 4-digit (to left of decimal point) frequencies to 1 or 2 places, the 3-digit frequencies to 2 or 3 places, and the 2 digit frequencies to 3 or 4 places, whatever suits you. --- Diane Hofstetter wrote: > > Does anyone know of a site on the net where I can > find a chart giving the frequencies for all the > notes on the piano?
