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.
The larger third that defines the major triad has a different emotional quality, it seems, from that of the smaller minor third that distinguishes the minor triad. There are other differences between the major and minor scales, of course, but the main thing is that tonic chord to which the music returns home so often.
