Jeremiah Clarke (c. 1674-1st December 1707) was an English baroque composer. Thought to have been born in London in 1674, Clarke was a pupil of John Blow at St Paul's Cathedral. He later became organist at the Chapel Royal. "A violent and hopeless passion for a very beautiful lady of a rank superior to his own" caused him to commit suicide by shooting himself. He was succeeded in his post by William Croft.
Christoph Willibald (von) Gluck (2 July 1714 - 15 November 1787) was a German composer, one of the most important opera composers of the Classical music era, particularly remembered for Orfeo ed Euridice. Gluck's operatic reforms, eliminating all that was undramatic, were a turning point in the history of the medium. Gluck's musical legacy was around 35 complete operas, together with numerous ballets and instrumental works.
Georg Philipp Telemann (14th March 1681–25th June 1767) was a German Baroque composer, born in Magdeburg. Self-taught in music, he studied law at the University of Leipzig. The most prolific composer of his era, he was a contemporary of Johann Sebastian Bach and a life-long friend of Georg Friedrich Händel. While in the present day Bach is generally thought of as the greater composer, Telemann was more widely renowned for his musical abilities during his lifetime.
