Modern string quartet refers to 20th- and 21st‑century writing and performance for the traditional two‑violins, viola, and cello ensemble, recasting the classical form with modernist, post‑tonal, minimalist, spectral, and post‑minimal languages. Hallmarks include extended techniques (sul ponticello, col legno, microtones, noise textures), flexible rhythm and meter, and harmonic vocabularies that range from atonal/serial procedures to modal, spectral, and neo‑tonal practices. Texture and timbre are often treated as primary compositional parameters, and form may be multi‑movement or a single, continuous arc. The genre bridges concert tradition and contemporary practice: canonical quartets commission and premiere new works, and living composers continuously expand the medium’s expressive palette in dialogue with a centuries‑old chamber tradition.

African-American classical refers to concert music in the Western art-music tradition written or led by African-American composers and performers. It encompasses orchestral, chamber, choral, operatic, and solo repertoire that speaks in the language of classical form and notation while drawing on the rhythms, scales, timbres, and stories of the African diaspora in the United States. Typical markers include the incorporation of spirituals, blues inflections, call-and-response textures, cakewalk and ragtime rhythms, and programmatic subjects tied to Black history and experience. Stylistically it ranges from late-Romantic symphonic writing through mid‑century modernism and post‑minimalism to today’s genre-fluid concert music.
