Violin Concerto no. 3 in G major, K.216 / Sinfonia Concertante in E-flat, K.364

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.

A serenade is a classical-period genre that originally denoted evening music performed outdoors, often offered to honor or woo someone. By the mid–late 18th century, it evolved into a multi-movement instrumental work closely related to the divertimento and cassation, typically lighter in character than a symphony and intended for social occasions. Serenades are tuneful, gracious, and often scored for small orchestra, wind ensemble, or strings, with movement types such as marches, minuets, and lyrical slow movements. Famous examples include Mozart’s Eine kleine Nachtmusik and the string serenades of Dvořák and Tchaikovsky.

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.
