I know this seems like a basic question, and in the traditional sense, I actually know how theirthey are related. Though, whilstwhile reading a book titled 'harmony'Harmony for computer musicians'Computer Musicians', I've come across a geometric image that is titled 'relationships'Relationships between keys on the circle of fifths'.
This is the image, page 26:
So, lets take C. C is is not connected in anywayany way to B-flat/A-sharp or to D. It is connected, however, connected to F and G, the author says that this was because they are the notes the lyethat lay directly a perfect fifth above/below note C. However, there is no explanation of why it is connected to E-flat, A-flat, D,flat, G-flat, B, E and A.
I have onno clue atas to what's going on. I have wasted a good few hours reading further into the circle of fifths and trying to figure out for myself why this geometric diagram is connected the whyway it is, but I can't figure it out. If anyone could help me, it would be VERY much appreciated.
