Watch the Week 4: Cycle of 4ths and 5ths online guitar lesson by Joe Pinnavaia from Fretboard Powerup

Cycle of 4ths and 5ths is a great tool for musicians because it shows us what notes are sharp or flat in a key signature as well as major and relative minor key centers. In this lesson, we take a look at how to use it in the practice of scales, chords and literally anything you would like to learn and move around the fretboard.
