- Chords Definition: A chord, in music, is any harmonic set of pitches consisting of two or more (usually three) notes (also called "pitches") that are heard as if sounding simultaneously. In everyday use by musical ensembles such as bands and orchestras, the three or more notes of a chord are often sounded together. However, the notes of a chord do not have to be played together at the same time: arpeggios and broken chords (these involve the notes of the chord played one after the other, rather than at the same time) may, for many practical and theoretical purposes, also constitute chords. Chords and sequences of chords are frequently used in modern West African and Oceanic music, Western classical music, and Western popular music; yet, they are absent from the music of many other parts of the world. In tonal Western classical music (music with a tonic key or "home key"), the most frequently encountered chords are triads, so called because they consist of three distinct notes: the root note, and Intervals of a third and a fifth above the root note. Further notes may be added to give tetrads such as seventh chords, the most commonly encountered example being the dominant seventh chord, consisting of the root note, the major third, the perfect fifth, and the minor seventh above the root.
