A Baroque orchestra is an ensemble for mixed instruments that existed during the Baroque era of Western Classical music, commonly identified as 1600–1750. Baroque orchestras are typically much smaller, in terms of the number of performers, than their Romantic-era counterparts. Baroque orchestras originated in France where Jean-Baptiste Lully added the newly re-designed hautbois (oboe) and transverse flutes to his orchestra, Les Vingt-quatre Violons du Roi. As well as violins and woodwinds, baroque orchestras often contained basso continuo instruments such as the theorbo, the lute, the harpsichord and the pipe organ.
