The final topic in pop aural skills is harmonic sequences, strings of chords whose roots move in a predictable interval pattern. Sequences are common in European classical music. Listen to Bach’s Chaconne from the D Minor Violin Partita or Contrapunctus VIII from The Art of Fugue for a million examples. Sequences are also pretty common in jazz. They are not so common in pop. But when people do use them, it can sound like a fun harmonic adventure.
Circle of fifths sequences
Many sequences are organized around the circle of fifths, so let’s start there. The basic idea is simple. Say you want to write a sequence in the key of C major. You find your chord roots by starting on C and moving through the key in counterclockwise circle of fifths order, like so: C, F, B, E, A, D, G, C.
