Understanding Non-Chord Tones: A Comprehensive Guide
Non-chord tones, also known as passing tones, suspension tones, or appoggiaturas, play a crucial role in the harmonic structure of music. These tones are not part of the chord currently being played but add color and depth to the music. In this article, we will delve into the various aspects of non-chord tones, their functions, and their impact on the overall sound of a piece.
What Are Non-Chord Tones?

| Appoggiatura | A tone that is added to a beat or a half-beat before resolving to a chord tone. | Adding a sense of anticipation and emphasis to the melody or accompaniment. |
