Neither chapter 13 nor chapter 14 actually include a list of terms.

Chapter 15: Further Techniques of Harmonic Development

Chromatic Substitution: The substitution of a chromatic harmony for an expected diatonic harmony.

Mixture of Mode: Borrowing a chord from the parallel minor mode.

Elision: The omission of an expected chord in a progression.

Multiple Chromatic Substitution: The substitution of several chromatic harmonies for expected diatonic harmonies.

Incomplete Progression: The omission of a chord which is expected as the harmonic goal of a progression.

Nontonic Beginning: A composition which starts on a harmony which is not the tonic, or in what might otherwise be the middle of a harmonic progression.

Chromatic Modulation: A modulatory progression with a chromatic triad as the goal/quasi-tonic.

Principle of Proximity: The principle that no consonant triad is far removed from the harmonic axis. If a harmony is distant in terms of a relation of the 5th, then it is close melodically (by a 2nd relation).

Chromatic Sequence: A sequence which moves chromatically. Such a progression is dependent on the repeated pattern (sequence) rather than the harmonic axis.
