"Baroque" generally refers to the symphonic and orchestral music composed between 1600 and 1750, which now forms a large core of the classical music canon. Baroque music is defined stylistically by heavy ornamentation, intense orchestrations, and a focus on tonality, harmony, and counterpoint. Some of the significant composers of the Baroque period are Johann Sebastian Bach, George Frideric Handel, Antonio Vivaldi, Georg Philipp Telemann, Johann Pachelbel, and Henry Purcell.

Johann Sebastian Bach was the most significant and well-known composer of the Baroque Era, which stretched from 1600 to 1750. Bach's signature elements—strong counterpoint, involved harmonies, and complex melodies—were extremely typical of Baroque music in general.

Johann Sebastian Bach is the composer most closely associated with the Baroque period. Bach's music, with its complex counterpoint melodies and harmonies, multilayered instrumentation, and formal structure, stands as representative of the entire era. Bach's music was seen as a high point of the Baroque era, and my of his works inspired developments away from Baroque music.

The Brandenburg Concertos are widely considered the pinnacle of Johann Sebastian Bach's musical compositions. Presented to the Margrave of Brandenburg-Schwedt in 1721, the six concertos are the perfect exemplar of Baroque composition, featuring layered harmonies of various instruments in an ornate contrapuntal orchestration. The Concertos most likely took years to compose, and were only fully completed in 1721.
