In music theory, a minor chord is a chord having a root, a minor third, and a perfect fifth. When a chord has these three notes alone, it is called a minor triad. Some minor triads with additional notes, such as the minor seventh chord, may also be called minor chords.
A minor triad can also be described as a minor third interval with a major third interval on top or as a root note, a note 3 semitones higher than the root, and a note 7 semitones higher than the root. Hence it can be represented by the integer notation {0, 3, 7}.
A major chord differs from a minor chord in having a major third above the root instead of a minor third. It can also be described as a major third with a minor third on top, in contrast to a minor chord, which has a minor third with a major third on top.
