Requiem / Ave verum corpus

The Classical period in Western art music (c. 1750–1820) is defined by clarity of form, balance of phrase, and transparent textures. Composers favored singable melodies, symmetrical four- and eight-bar phrases, and functional harmony that modulates to closely related keys. Hallmark forms such as the symphony, string quartet, sonata, and classical concerto were standardized, often using sonata form, theme-and-variations, minuet and trio, and rondo designs. Orchestras expanded beyond strings to include standardized pairs of woodwinds and horns, with trumpets and timpani for ceremonial weight, while the fortepiano gradually replaced the harpsichord. The style pivoted away from the dense counterpoint of the late Baroque toward a more galant, conversational musical rhetoric. It culminated in the Viennese masters—Haydn, Mozart, and the early Beethoven—whose works crystallized the era’s ideals and prepared the way for Romanticism.

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.
