Baroque music (UK: /bəˈrɒk/ or US: /bəˈroʊk/) 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 galant style). Baroque music forms a major portion of the "classical music" canon, and continues to be widely studied, performed, and listened to. Key composers of the Baroque era include Jacopo Peri, who wrote the first operas; Alessandro Stradella, who originated the concerto grosso style; and Arcangelo Corelli, who was one of the first composers to publish widely and have his music performed across Europe.
The Baroque period saw the formalization of common-practice tonality, an approach to writing music in which a song or piece is written in a particular key; this type of harmony has continued to be used extensively in Western classical and popular music. Baroque composers experimented with finding a fuller sound for each instrumental part, leading to the creation of the modern orchestra; modernised musical notation, including developing figured bass; and developed new instrumental playing techniques. Baroque music expanded the size, range, and complexity of instrumental performance, and also established the mixed vocal/instrumental forms of opera, cantata and oratorio and the instrumental forms of the solo concerto and sonata as musical genres. Dense, complex polyphonic music, in which multiple independent melody lines were performed simultaneously.
