Karl Amadeus Hartmann

Austro-German modernism is a current in early 20th‑century classical music centered in Vienna, Berlin, and other cultural hubs of the German‑speaking world. It is marked by the break with late‑Romantic tonality through chromatic saturation, atonality, and ultimately systematic twelve‑tone/serial procedures; a heightened, often expressionist intensity of gesture; concentrated motivic work; and refined attention to timbre (including Klangfarbenmelodie). While many composers retained or reimagined traditional forms, their harmonic language, rhythm, and orchestration pursued a radical new expressivity. Beyond its signature pitch techniques, the movement embraced new vocal practices (such as Sprechstimme), chamber ensembles of novel makeup, and an aesthetics that oscillated between ecstatic subjectivity and ascetic concentration. Its innovations set the groundwork for much of 20th‑ and 21st‑century concert music.

Early modern classical is Western art music from the early modern era, spanning roughly the 1500s through the mid-1700s. It includes late Renaissance polyphony and the major stylistic changes of the Baroque period, such as the rise of tonal harmony, basso continuo, virtuosic instrumental writing, and dramatic vocal genres. Typical sound worlds range from intricate a cappella choral counterpoint to richly ornamented solo/ensemble music with harpsichord and continuo bass, and from courtly dance suites to large-scale sacred works and early opera.
