Symphonic repertoire refers to the collection of musical works composed for orchestras, typically featuring a full range of instruments. This repertoire includes various genres, such as symphonies, concertos, and overtures, and spans different historical periods, from the Classical era to contemporary compositions. Orchestras perform these works in concert halls, showcasing the rich textures and dynamics that come from combining strings, woodwinds, brass, and percussion. Notable composers in the symphonic repertoire include Ludwig van Beethoven, Wolfgang Amadeus Mozart, and Gustav Mahler, each contributing significantly to the evolution of orchestral music.
