CHROMATIC TO DIATONIC
The pivot chord will be chromatic in the old key and diatonic in the new key using chromatic to diatonic modulations.

CHROMATIC TO CHROMATIC
The pivot chord will be chromatic in both the old and new keys using chromatic to chromatic modulations.

ENHARMONIC MODULATION
An enharmonic modulation occurs when the pivot chord sounds the same in both keys and is enharmonically spelled in the new key.

CHANGE OF MODE
A change of mode is a modulation that occurs when a major or minor key modulates to its parallel key.
