Chapter 3 of Auditory Neuroscience discusses the pitch intervals used western music in great detail. For convenience, a table of fundamental frequencies for equal-tempered scale is copied below from http://www.phy.mtu.edu/~suits/notefreqs.html.
By convention A4 = 440 Hz
Notes are separated by "semitone" intervals. There are 12 seimtones in each octave, and fundamental frequencies are logarithmically spaced, so the each note fundamental frequency is 2(1/12) = 1.0595 times the previous frequency.
The wavelength values assume a speed of sound = 345 m/s
("Middle C" is C4 )
