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 difference between chords and power chords. A chord is the combination of three or more notes played simultaneously. Known as triads, chords contain a root, third and fifth note, at least. Power chords, on the other hand, are dyads. They are composed of a root and fifth note only, though they can also include an additional octave note.
