The Baroque period was a revolutionary time in music history that saw a full embrace of polyphony, ornamentation, and harmonic sophistication. After its inception in Italy, Baroque music expanded throughout Europe thanks to composers like Johann Sebastian Bach and George Frideric Handel.
Origin in Italy
The early Baroque era of music centered in Italy. Italian composers based in Rome and its surroundings composed music that drew on the traditions of the Renaissance era but also expanded its harmonic and ornamental boundaries. Notable Italian Baroque composers include Alessandro Scarlatti (and his son Domenico Scarlatti), Antonio Corelli, and Claudio Monteverdi. Antonio Vivaldi was the last major Italian Baroque composer. He worked in the later Baroque era, overlapping with George Frideric Handel and Johann Sebastian Bach.
German influence
As musicians traveled throughout Europe, the Baroque style caught on, and new composers added new elements. The English composer Henry Purcell and French composers like Jean-Baptiste Lully and Jean-Phillippe Rameau made marks, but it was the German school of Baroque music that was most influential. Georg Philipp Telemann, Michael Praetorius, Johann Pachelbel, and most of all Johann Sebastian Bach helped define the high Baroque period. Another prominent German was George Frideric Handel, although he spent nearly his entire career in England.
End of an era
The Baroque period's end is tied to the death of Bach in 1750. The second half of the eighteenth century and early nineteenth century marked the Classical period, where composers like Wolfgang Amadeus Mozart and Franz Joseph Haydn built on the foundation laid by Baroque composers.(from internet)
