Understanding Intervals

Intervals are the building blocks of melody and harmony. Learn their names, sizes and shapes, and find them anywhere on the neck.

By the end you'll be able to:

  • Name any interval by number and quality
  • Connect interval names to half-step sizes and fretboard shapes
  • Find and recognise intervals from any root
