What is a Chromatic Harmony?

Chromatic harmony refers to the use of chords and harmonic progressions that include notes outside the main scale or key of a piece of music. Instead of relying only on the notes from a single scale, chromatic harmony introduces additional tones from the chromatic scale to create richer and more varied harmonic movement.

In traditional tonal harmony, chords are usually built from the notes of a particular key. With chromatic harmony, composers may borrow chords from other keys, alter chord tones, or use notes that do not belong to the original scale. These chromatic notes often create temporary tension or color that resolves back into the main key.

Chromatic harmony is widely used in classical, jazz, and film music to add emotional depth and complexity. Composers from the Romantic period, such as Richard Wagner and Frédéric Chopin, used extensive chromatic harmony to create expressive and dramatic harmonic progressions. Today, it remains an important technique for expanding the range of harmonic possibilities in many musical styles.
