In [[music theory]], a '''nondominant seventh chord''' is a [[chord (music)|chord]] which is a [[diatonic and chromatic|diatonic chord]] that is a [[seventh chord]] but that does not possess [[dominant (music)|dominant]] [[diatonic function|function]]<ref name="B&S 229"/> and thus is ''not'' a [[dominant seventh chord]].

To [[musical analysis|analyze]] seventh chords indicate the quality of the triad; [[major chord|major]]: I, [[minor chord|minor]]: ii, half-diminished: vii{{music|halfdim}}, or [[augmented chord|augmented]]: III+; and the quality of the [[seventh (chord)|seventh]]; same: <sup>7</sup>, or different: <math>_M^7</math> or <math>_m^7</math>.<ref name="B&S 229"/> In [[macro analysis]] indicate the [[root (chord)|root]] and [[Major and minor|chord quality]], and add <sup>7</sup>, thus a seventh chord on ii in C major (minor minor seventh) would be d<sup>7</sup>.<ref name="B&S 230"/>
 
As with dominant seventh chords, nondominant seventh chords usually progress according to the [[circle progression]], thus [[augmented major seventh chord|III+]]<math>_M^7</math> resolves to vi or [[subdominant|VI]],<ref name="B&S 232">Benward & Saker (2003), p.232.</ref> for example.
