Are you one of those "musicmen" that doesn't understand the difference between an R sharp and a Be Flat? You indicate your intelligence and understanding by your interpretation of the "music" at hand. But, maybe I'm just being moody right now.
There is no "R" in the musical scale.
it's
A, A#, B, C, C#, D, D#, E, F, F#, G, G#
now, Indian music (as in Ravi Shankar) they have a lot more....
