American orchestra refers to the tradition and sound-world of symphonic and concert orchestras based in the United States. It is centered on large ensemble performance (strings, woodwinds, brass, percussion, and sometimes harp, piano/celesta, and auxiliary instruments) across the Western classical repertoire, but it is also shaped by specifically American institutional history, performance practice, commissioning culture, and repertoire preferences. In practical listening terms, it often points to recordings and performances by U.S. orchestras and conductors, spanning Romantic symphonies, late-Romantic tone poems, 20th/21st-century concert music, and American concert works (including nationalist, modernist, and film-influenced symphonic idioms).

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.
