In this lesson you'll learn 7 different exercises for mastering the Circle of 5ths all around the keyboard. The Circle of 5ths is one of the most prominent harmonic devices in Western music. It organizes the key signatures by number of accidentals in both directions, and segments of the circle show up in harmonic progressions in nearly all styles of music--rock, pop, blues, jazz, folk, you name it. Many of the most common harmonic cycles and resolutions (V-I, ii-V-I, vi-ii-V-I) stem directly from the circle, so it's crucial to know your way around it backwards and forwards. These 7 exercises will help you get there.
