    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 ‘root’) of the
 chord, the second note is the ‘third’ of the chord, and the last note is
 the ‘fifth’ 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.
