Primary triads in C Play (helpÂ·info) . In music, a primary triad is one of the three triads, or three-note chords built from major or minor thirds, most important in tonal and diatonic music, as opposed to an auxiliary triad or secondary triad. Each triad found in a diatonic key corresponds to a particular diatonic function.
Because a triad consists of two stacked thirds, only the actual notes of the triad in a melody can avoid forming a major or minor second with one or other or its notes. In this way, a triad imposes a hierarchy on melody by highlighting which notes are part of the harmony (consonant) and which are not (dissonant). There are seven possible diatonic triads in C major (see triads definition), so it is possible to harmonise any note of the C major scale with a triad that will make it consonant.
