Octaves, or perfect 8th intervals, are a great way for adding an extra layer of depth to your solos, no matter what your preferred style; many of the greats of jazz, rock, blues and metal have all incorporated octaves into their solos and guitar licks.
If your single-note guitar playing is sounding a bit too shallow, doubling with octaves can be a great way to bring it to life. You don’t have to know every scale on the fretboard to get to grips with guitar octaves, but you will need a rough idea of how the notes are laid out, while techniques, such as string muting or fingerpicking, will come in handy.
