Music Glossary

Chord

Three or more notes played together to create harmony.

A chord is a group of notes — usually three or more — sounded together to create harmony, the vertical dimension of music that sits underneath melody. The most basic chords are triads, built from a root note plus the third and fifth above it; major triads sound bright and resolved, minor triads sound darker or sadder. Chords are the harmonic backbone of nearly all popular music: a song's chord progression (the sequence of chords over time) shapes its emotional movement, and an enormous catalogue of songs is built from just three or four common chords repeated in different orders.
