Which compositional technique involves the use of chromatic harmonies?

Impressionism is characterized by a focus on atmosphere and mood rather than strict structural forms. In music, this often manifests through the use of complex harmonies, including chromatic harmonies, which are essential in creating the lush, fluid soundscapes associated with this style. Composers like Claude Debussy and Maurice Ravel utilized chromaticism to evoke emotional responses and to blur harmonic boundaries, leading to a more nuanced and rich musical experience.

In contrast, minimalism typically emphasizes simplicity and repetition, while neoclassicism often draws on the clarity and forms of earlier musical eras, which tend to favor diatonic harmony. Folk style usually incorporates traditional melodies and chords that are often based on major and minor scales, avoiding the complexity of chromaticism.
