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.

A requiem is a musical setting of the Roman Catholic Mass for the Dead (Missa pro defunctis). Historically rooted in Latin liturgy, it sets movements such as the Introit, Kyrie, (historically) the Sequence Dies irae, Offertory, Sanctus, Agnus Dei, and Communion, and often includes additional responsories like Libera me and In paradisum. While the earliest requiems were monophonic chants, the genre became a showcase for polyphonic and later symphonic choral writing. Renaissance composers wrote austere, modal settings; Classical and Romantic composers expanded the forces and dramatic scope; and 20th–21st century composers reimagined the form with new languages, from neo-modal and impressionistic harmonies to avant‑garde sonorities. Today, requiems appear both in liturgy and as concert works, symbolizing collective mourning, remembrance, and spiritual reflection.

Classical music is the notated art-music tradition of Europe and its global descendants, characterized by durable forms, carefully codified harmony and counterpoint, and a literate score-based practice. The term “classical” can refer broadly to the entire Western art-music lineage from the Medieval era to today, not just the Classical period (c. 1750s–1820s). It privileges long-form structures (such as symphonies, sonatas, concertos, masses, and operas), functional or modal harmony, thematic development, and timbral nuance across ensembles ranging from solo instruments to full orchestras and choirs. Across centuries, the style evolved from chant and modal polyphony to tonal harmony, and later to post-tonal idioms, while maintaining a shared emphasis on written notation, performance practice, and craft.
