George Frideric Handel and Michael Tippett, both were of which musical profession?
Michael Tippett Sir Michael Kemp Tippett {'1': ", '2': ", '3': ", '4': "} (2 January 1905 – 8 January 1998) was an English composer who rose to prominence during and immediately after the Second World War. In his lifetime he was sometimes ranked with his contemporary Benjamin Britten as one of the leading British composers of the 20th century. Among his best-known works are the oratorio "A Child of Our Time", the orchestral "Fantasia Concertante on a Theme of Corelli", and the opera "The Midsummer Marriage".
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.
