Be a Better Acoustic Guitarist: How to Use Thirds to Spice Up Your Licks

An interval is the distance between two notes: If you walk up a scale, the distance from any note to the next note is called a second, and the distance from the first note to the one above the second is called a third. Thirds are often used to create guitar riffs and can also sound great in an improvisational setting.

Guitarist Andrew DuBrock offers a detailed look at the ways thirds are constructed, how to build thirds from scales, how to compose riffs using thirds, and how to improvise using thirds.
