Enharmonic is the identical tone or chord included within a different key or scale. Diatonic means within the key or the tones (notes) included within that key.To diminish or augment a chord or interval is known as its dissonance.
Understanding chord dissonance is crucial to maintaining key diatonic when composing or performing.
