Composing Music by William Russo: Chapter 9 (Cont.)

Changing Tones

Changing tones are two non-chord tones that are on either side of a chord tone, to which they resolve.

Reverse Neighboring Tones

A reverse neighboring tone is preceded by a chord tone that is a major or minor 2nd above or below it, and it is followed by a skip to a chord tone.

Escape Tones

An escape tone is a non-chord tone that moves from a chord tone by a skip (some sources say step) and proceeds to another chord tone by a skip.
