George Frideric Handel
Along with J.S. Bach (1685-1750) and Antonio Vivaldi (1678-1741), George Frideric Handel (1685-1759) is widely regarded as among the most significant composers of the Baroque era, and certainly his Messiah is one of the most-performed works of all time. Handel was born in Germany but became a British subject in 1727, and it was from his naturalized home in London that he gained fame as a composer, primarily for his operas and oratorios.
Among his instrumental works, both Water Music and Music for the Royal Fireworks remain great favorites. The 18 concerti grossi that comprise his Opus 3 and Opus 6 are not as well-known, but they nonetheless provide some of the finest examples of the genre. All of Handel's 12 Concerti Grossi, Op. 6 were composed in less than a month in the fall of 1739, and primarily were written to serve as interludes during performances of his oratorios and other choral works.
The Passacaglia is drawn from the 7th of Handel’s 12 harpsichord suites, and it was arranged for violin and viola in 1894 by Johan Halvorsen(1864-1935), a Norwegian composer and conductor.
