The crazy thing is we study the circle of 5ths and play the circle of 4ths. Starting on C the circle of 4ths moves in perfect 4ths through all 12 notes, C F Bb Eb Ab Db F# B E A D G C Do you see the word bead used twice, those two words B E A D and Bb Eb Ab Db use 8 of the 12 notes, that leaves only 4 notes to learn. It doesn't jump out at you in 5ths order, D E A B doesn't roll off the tongue lol, and we don't play much in circle of 5th, it's like paddling upstream. Hey Joe is a good example of using the circle of 5ths, but by far 4ths are the way we go, it's the whole tension/release thing. You can also play a diatonic circle of 4ths, C F B E A D G C C F Bdim Em Am Dm G C or Cmaj7 Fmaj7 Bm7b5 Em7 Am7 Dm7 G7 I see all these tension/release moves here. C to F creates tension. G7 to C is that sense of release or resolution, the V7 to I move. Play the progression and see how totally "song friendly" it is. In summary, Circle of 5ths go to the right,,, Circle of 4ths go to the left and is more musical. It's the way chords like to progress.
