A chamber orchestra is a small ensemble of musicians that typically consists of 15 to 40 players. Unlike a full symphony orchestra, which can have over 100 musicians, chamber orchestras focus on a more intimate sound. They often perform classical music, including works from composers like Mozart and Haydn, and are known for their versatility in repertoire. Chamber orchestras usually feature a mix of string, woodwind, brass, and percussion instruments. This allows them to perform a wide range of music, from baroque to contemporary pieces. Their smaller size enables greater interaction among musicians and a more personal experience for the audience.
