Baroque music refers to the period or dominant style of Western classical music composed from about 1600 to 1750. The Baroque style followed the Renaissance period, and was followed in turn by the Classical period after a short transition. The Baroque period is divided into three major phases: early, middle, and late. Overlapping in time, they are conventionally dated from 1580 to 1650, from 1630 to 1700, and from 1680 to 1750. Baroque music forms a major portion of the "classical music" canon, and is widely studied, performed, and listened to. The term "baroque" comes from the Portuguese word barroco, meaning "misshapen pearl". The works of George Frideric Handel and Johann Sebastian Bach are considered the pinnacle of the Baroque period. Other key composers of the Baroque era include Claudio Monteverdi, Domenico Scarlatti, Alessandro Scarlatti, Alessandro Stradella, Tomaso Albinoni, Johann Pachelbel, Henry Purcell, Antonio Vivaldi, Georg Philipp Telemann, Jean-Baptiste Lully, Jean-Philippe Rameau, Marc-Antoine Charpentier, Arcangelo Corelli, François Couperin, Johann Hermann Schein, Heinrich Schütz, Samuel Scheidt, Dieterich Buxtehude, Gaspar Sanz, José de Nebra, Antonio Soler, Carlos Seixas and others.

Renaissance music is traditionally understood to cover European music of the 15th and 16th centuries, later than the Renaissance era as it is understood in other disciplines. Rather than starting from the early 14th-century ars nova, the Trecento music was treated by musicology as a coda to Medieval music and the new era dated from the rise of triadic harmony and the spread of the contenance angloise style from Britain to the Burgundian School. A convenient watershed for its end is the adoption of basso continuo at the beginning of the Baroque period.
