*EDIT Sep 2015* Om lies between the music notes of C and C#(Sharp). The Third eye is "A".
I've been looking for the answer to this too. I am not a musical performer, however, I believe it is the musical note "A". If om vibrates and activates our 7th chakra, which is a connection the body has with the universal energy and the universe, and if the "sound of nature" vibrates at an "A" also, then the note "A" should be the correct musical note for om.
p.s. this is my conjecture at this point in time.
