The quality of a triad is determined by the precise arrangement of
its intervals. Tertian triads can be described as a series of three
notes. The first element is the root note (or simply ârootâ) of the
chord, the second note is the âthirdâ of the chord, and the last note is
the âfifthâ of the chord. These are described below:

There are various types of seventh chords depending on the quality of
the original chord and the quality of the seventh added.
Five common types of seventh chords have standard symbols. The chord
quality indications are sometimes superscripted and sometimes not (e.g.
Dm7, Dm^7, and D^m7 are all identical). The last three chords are not
commonly used except in jazz.
