Kapustin:Eight Concert Etudes

Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.

Impressionism in music is a late-19th- and early-20th-century style that prioritizes color, atmosphere, and suggestion over overt drama and functional harmonic progressions. Originating in France, it parallels the visual arts movement in its fascination with light, timbre, and fleeting impressions. Musically, the style favors modal, pentatonic, and whole‑tone materials; parallel (planed) chords; unresolved dissonances; and ambiguous tonal centers. Rhythms are flexible and often blur a sense of strong meter, while textures shimmer through delicate orchestration, pedal tones, and arpeggiated figures. Rather than strict sonata designs, impressionist works tend to be episodic, evocative, and programmatic, conjuring landscapes, water, night, and dreamlike states.
