In music theory, a minor chord ( play D minor chord (help·info)) is a chord having a root, a minor third, and a perfect fifth.[2] 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 ( play (help·info)) 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. They both contain fifths, because a major third (4 semitones) plus a minor third (3 semitones) equals a fifth (7 semitones).
A diminished chord is a minor chord with a lowered fifth.  play (help·info)
An example of a minor chord is the C minor chord, which consists of the notes C (root), E♭ (minor third) and G (perfect fifth):

The minor chord, along with the major chord, is one of the basic building blocks of tonal music and the common practice period. In Western music, a minor chord, in comparison, “sounds darker than a major chord”[3] but is still considered highly consonant, stable, or as not requiring resolution.
Acoustic consonance of the minor chord[edit]
A unique particularity of the minor chord is that this is the only chord of three notes in which the three notes have one harmonic – hearable and with a not too high row – in common (more or less exactly, depending on the tuning system used) : This harmonic, common to the three notes, is situated 2 octaves above the high note of the chord : This is the harm
