I've always struggled with the immediate application of theory, without it I'll usually forget the concept. Besides being able to construct basic chords in their relative key has anyone else found good uses for the circle of 5th's?
Exactly! A great way to learn the blues (I-IV-V) in all 12 keys! Move counterclockwise and it's the IV, move clockwise and it's the V.View attachment 791
If you take both rings the inner ring are the relative minors of the major chords in the outer ring(C#m is the vi chord in the key of E for example). If you take either ring going counter clockwise is always V-I and clockwise is always IV - I so you can also deduct the IV chord and the V chord from the circle of fifths.
If you take A for example D is the IV chord, E is the V chord and F#m is the realtor minor.
