Baroque music is a style of Western music composed from approximately 1600 to 1750. This era follows the Renaissance, and was followed in turn by the Classical era. The word "baroque" purportedly comes from the Portuguese word barroco, meaning misshapen pearl, a negative description of the ornate and heavily ornamented music of this period.
During the Baroque period, composers and performers used more elaborate musical ornamentation, made changes in musical notation, and developed new instrumental playing techniques. Baroque music expanded the size, range, and complexity of instrumental performance, and also established opera, cantata, oratorio, concerto, and sonata as musical genres. Many musical terms and concepts from this era are still in use today.
