Non-tendency Tones

Definition

Non-tendency tones, also known as non-chord tones, are melodic notes that do not belong to the underlying harmony. They create temporary dissonance and add color and interest to music before resolving to a chord tone.

Analogy

Imagine you're painting a picture with different colors, but then you decide to add a splash of an unexpected color that doesn't quite match. That unexpected color represents a non-tendency tone - it adds intrigue and contrast before blending back into the harmonious colors.

Passing Tone: A passing tone is a non-tendency tone that connects two chord tones by stepwise motion. It "passes" between them, creating smooth melodic movement.

Suspension: A suspension occurs when a note from the previous chord is held over into the next chord, creating dissonance until it resolves downward by step. Suspensions are one type of non-tendency tone.

Appogiatura: An appogiatura is a non-chord tone that approaches its resolution note by leap (usually from above) instead of stepwise motion. It creates tension before resolving melodically.
