George Frideric Handel and Michael Tippett, both were of which musical profession?
George Frideric Handel George Frideric (or Frederick) Handel ( ; born Georg Friedrich Händel ] ; 23 February 1685 (O.S.) [(N.S.) 5 March] – 14 April 1759) was a German, later British, baroque composer who spent the bulk of his career in London, becoming well known for his operas, oratorios, anthems, and organ concertos. Handel received important training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712; he became a naturalised British subject in 1727. He was strongly influenced both by the great composers of the Italian Baroque and by the middle-German polyphonic choral tradition.
Elisabetta Pilotti-Schiavonetti Elisabetta Pilotti-Schiavonetti (  1680  – 5 May 1742) was an Italian operatic soprano who was associated with the House of Hanover. She was one of the leading prima donnas at the Queen's Theatre in the Haymarket (it later became the "King's Theatre" after King George I's accession in 1714) from 1710 to 1717. She is best remembered today for creating roles in at least four operas by George Frideric Handel, possibly five. Three of the roles that Handel wrote specifically for her were sorceresses, and the demands of those roles indicate that she possessed an exceptional voice capable of both dramatic power and technical agility. She is said to have had a bitter rivalry with the Queen's other leading soprano, Isabella Girardeau.
