About Musical Intervals

A musical interval is the distance between two pitches. Understanding intervals is fundamental to music theory, as they form the building blocks of melodies and harmonies.

Perfect Intervals

Unison, 4th, 5th, and octave. These are the most consonant and stable sounding intervals.

Major Intervals

2nd, 3rd, 6th, and 7th. These create bright, happy sounding harmonies.

Minor Intervals

One semitone smaller than major. Creates darker, more melancholic sounds.

Tritone

6 semitones, the most dissonant interval. Creates tension that wants to resolve.
