Hi, I'm quite interested in harmonic theory etc and I'd like to
know how the frequencies of each note are related.
Can anyone provide me with a list of example frequencies for all
twelve notes ( i.e. A = 440 Hz, A# = ??? etc... ).
Also, how can you compute the frequency difference between notes ? e.g.
what happens to the frequency when you raise pitch by, say, a P4 ?
Any help, or pointers to references ( this may not even be the right
place to ask (8^) ) will be appreciated.
Thanks in advance, Dave.

| 771.1 | Physics problem | ANT::JACQUES | Fri Aug 12 1988 09:21 | 9 | |
I'll have to check through my Physics book. I have a book at home
entitled "The Physics of Music". It's a little paperback book.
I think this was covered in Heat, Light, and Sound (Physics II),
but I don't remember the formulas off hand.
Any particular reason you ask, or is it just for curiousity sake?

| 771.2 | Factor of 12th root of 2. | FLOWER::JASNIEWSKI | Mon Aug 15 1988 11:07 | 10 | |
Each note in a chromatic scale is seperated in frequency by
a multiple which is the twelth root of 2. The way you get to A#
from A=440hz is to multiply 440 by 12 Root 2. To get to G# from
A=440, divide by the 12 Root 2 factor.
You can generate all the frequencies in this way -

Aha ! Should've been obvious really ! That's what I was after...
Thanks Joe,
