See the cycle of 4ths, 5ths, key signatures, parallel minors and roman numerals!
The SWS takes you around the cycle of 4ths (moving anti-clockwise) as well as the cycle of 5ths (moving clockwise)
Should you start in C, then all keys moving clockwise increase with one # at a time.
Similarly, should you move anti clock-wise, you can ad another b for each key.
The inner circle of chords display the parallel minors, the middle circle the major chords (I IV and V).
Musical harmony is all about understanding all these layers individually, as well as how they interact with each other.
The Intermediate Guitar Course has the full story. In the course we learn how all chords can have a pentatonic shape paired with each chord.
The Song Writers Swivel can with this in mind be expanded into: Key – Chord Number – Pentatonic scale.
Make sure you can apply this concept in any key.
