Harmonic Intervals

What Are Harmonic Intervals?

A harmonic interval occurs when you play two different musical notes at the exact same time, creating a two-note chord. You measure the distance by counting up from the bottom note — count the white keys on your piano (or the lines and spaces of the staff above). In this lesson we explore larger distances: fourths, fifths, and sixths.

Why Do These Intervals Matter?

Fourths, fifths, and sixths form the backbone of harmony and chord building in almost every style of music. Fifths sound incredibly hollow and strong, often used in rock 'power chords,' while fourths sound open and slightly tense. Sixths offer a sweet, warm, and highly pleasing sound that adds beautiful emotion to your melodies.

How to Find and Play Them

To play a fifth, skip three white keys between your fingers, like playing C and G together. To make a fourth, leave just two white keys in between, such as C and F. For a sixth, widen your hand span to leave four white keys empty in the middle, playing C and A simultaneously.
