Sinfonietta, op. 1 / Serenade, op. 31 / Now Sleeps the Crimson Petal / Nocturne, op. 60

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.

Vocal music is music in which one or more singers carry the primary musical line, whether accompanied by instruments or sung a cappella (without any non‑vocal instrumental accompaniment). If singing is present but not featured prominently, the piece is typically treated as instrumental music. By contrast, vocal music foregrounds the human voice—its words, melody, timbre, and expressive nuance—across an enormous range of styles from chant and folk song to opera, pop, and hip hop.
