The subject says it all. I'm looking for some kind soul to give me the #
of Hz for each note (A flat, A, A sharp, B...). If anyone has one, or
knows of an FTP site that might, please let me know.

I can be reached at darr...@aol.com.

Thanks in advance.

A below middle-C is 440 Hz. All other notes are related to that by
the 12th root of 2 for each half step away from A-440.

What does this have to do with the C programming language?

Hope this helps.

The frequencies of eight octaves of musical notes (including flats and
sharps) are listed in:

_The New Peter Norton Programmer's Guide to the IBM PC & PS/2_ by
Peter Norton and Richard Wilton, Microsoft Press, 1988, p. 147.

There are way too many for me to retype here for you :-).

I don't have a table on hand but it is easy to work out... in
[some particular standard], A above middle C is defined as 440Hz. A
semitone rise in an even-tempered scale corresponsds to multiplying
the frequency by the 12th-root of 2. (ie 2^(1/12)

soo. A = 440
A# = 440 * 2^(1/12)
B = 440 * 2^(1/12) * 2^(1/12)
= 440 * 2^(2/12)
.....
A' = 440 * 2^(12/12)
= 440 * 2

which as you can see is all based on the fact that an octave is
a doubling of frequency and there are 12 semitones in an octave. To
go the other way (down), logically you divide by the 12th-root of 2..

So what do you mean with below middle-C? From A to A:
440, 466, 494, 523, 554, 587, 622, 659, 699, 739, 784, 828, 880
but this is only one of the many possibilities. Another one is:
440, ..., 495, 528, ..., 594, ..., 660, 704, ..., 792, ..., 880
However this one gives a-flat = 844.8, g-sharp = 825.

The first letter stands for the note
the second letter (if present) stands for the alteration (S=sharp, F=Flat
none=natural, I've included ES, FF, BS and CF even if it was not necessary)
the number stand for the octave #

so CS5 = C sharp in the fifth octave

I tried to e-mail this post to original poster but as I didn't succeed
I had to post it (all though it is probably not supposed to be in this
newsgroup)

The scale is built up by dividing an octave into parts. An octave is always
a relation of 2:1 in frequency (i.e. A'=440Hz and A''=880Hz). If you do it the
simple way and just divide it evenly in 12 tones ( that is the standard western
scale) you get the tempered scale, just as mentioned by the first posting (Mark
Linton). In music you usally mesure the distance between notes in cents, and
you
get 1200 cents on an octave. This would result in (by multiplying with the 12
root of two to A=440Hz)

C 261,6 Hz
277.2
D 293.7
311.1
E 329.6
F 349.2
370.0
G 392.0
415.3
A 440.0
466.2
B 493.9
C'' 523.3

But as many probably know the music is often built up of chords, and
chords are built of notes that are (for instance) a major third and a fifth
appart (C-E-G) and then this notes should be frequency correct related. That
is,
a major third should be 5:4 in frequency and a fifth 3:2. If you look at the
scale above this is not true. The scale were this is correct is called
a diactonic scale but this one can be built up in many different ways since
you cannot have all tones frequency correct related. A piano or a synth is
mostly tuned in a equally tempered scale whilst a guitar often is tuned
diactonic (since the strings are at fifth.s from each others).

If you are further interested in the subject I suggest some book about
Musical Acoustics for instance

Musical Acoustics by Donald E. Hall

Hope this clears it up,

|So what do you mean with below middle-C? From A to A:
| 440, 466, 494, 523, 554, 587, 622, 659, 699, 739, 784, 828, 880

Be careful with rounding (or truncating) those frequencies here. One
of the most important aspects of a `proper' major scale are the
harmonic progressions, i.e. a ratio of 3/2 for a quint/prime is much
more important than a proper equidistance distribution between those
tones. I, for myself, prefer the harmonic scales, i.e.

A= 440, E (quint of A) = 3/2*440 = 660, B (quint of E) = 3/2*660=
990 == (lower octave) 445, etc. etc.

Using this harmonic progression, the results are conform the idea
that e.g. f-sharp > g-flat.

|Nothing.

Allow me to correct this ;-)

char up[] = "A A#B C C#D D#E F F#G G#";
char dn[] = "A AbG GbF E EbD DbC B Bb";

int main() {

double f;
int i, j;

f= 440.0;
printf("up scale:\n");
for (i= 0, j= 0; i < 12; i++) {
printf(" %2.2s: %f\n", up+2*j, f);
f= 3.0/2.0*f;

f/= 2.0;
j= (j+7)%12;

f= 880.0;

f= 2.0/3.0*f;

Hello, Darrin!

Start with the 2nd space treble clef _A_ = 440. To go up a 1/2
step, multiply by the 12th root of 2 ~ 1.059463, to go down, divide
by it. The frequency will double or halve as you go up or down
