I've made it to the Circle of Fifths in the newbies book.
Pages 92 and 93:
The creation of the Circle of Fifths is the very foundation of modern Western music theory, which is why we talk about it so much in this book.
Along with being your best friend for deciphering key signatures on sight, the Circle of Fifths is just as essential in writing music, because its clever design is helpful in composing and harmonizing melodies, building chords, and moving to different keys within a composition.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
