George Frideric Handel (Friday, 23 February 1685 - Saturday, 14 April 1759) was a German-born Baroque composer who is famous for his operas, oratorios and concerti grossi. Born as Georg Friedrich Handel in Halle, he spent most of his adult life in England, becoming a subject of the British crown on 22 January 1727. His most famous works are Messiah, an oratorio set to texts from the King James Bible; Water Music; and Music for the Royal Fireworks. Strongly influenced by the techniques of the great composers of the Italian Baroque and the English composer Henry Purcell, his music was known to many significant composers who came after him, including Haydn, Mozart, and Beethoven.

Handel's compositions include 42 operas; 29 oratorios; more than 120 cantatas, trios and duets; numerous arias; chamber music; a large number of ecumenical pieces; odes and serenatas; and sixteen organ concerti. His most famous work, the Messiah oratorio with its "Hallelujah" chorus, is among the most popular works in choral music and has become a centerpiece of the Christmas season. Also popular are the Opus 3 and 6 Concerti Grossi, as well as "The Cuckoo and the Nightingale", in which birds are heard calling during passages played in different keys representing the vocal ranges of two birds. Also notable are his sixteen keyboard suites, especially The Harmonious Blacksmith.

Handel introduced various previously uncommon musical instruments in his works: the viola d'amore and violetta marina (Orlando), the lute (Ode for St. Cecilia's Day), three trombones (Saul), clarinets or small high cornets (Tamerlano), theorbo, French horn (Water Music), lyrichord, double bassoon, viola da gamba, bell chimes, positive organ, and harp (Giulio Cesare, Alexander's Feast).
