River Thames
The Water Music composed by George Frideric Handel premiered on 17 July 1717, when King George I requested a concert on the River Thames. The concert was performed for King George I on his barge and he is said to have enjoyed it so much that he ordered the 50 exhausted musicians to play the suites three times on the trip.
Parnasso in festa
The German-born Handel had been resident in London since 1712 and had there achieved great success as a composer of Italian operas. He had also enjoyed the patronage of monarchs Queen Anne, George I and George II and other members of the royal family and had been commissioned by them to compose numerous pieces of music for worship services in the royal chapels as well as for other royal occasions. Handel enjoyed a particularly warm and close relationship with Anne, Princess Royal, eldest daughter of George II, who supported his opera seasons, was an accomplished musician herself, and to whom Handel even gave private lessons – although he did not enjoy teaching, he made an exception in her case. Handel composed the anthem for her wedding, "This is the day which the Lord hath made", to Biblical texts selected by Anne herself, which was performed at her marriage to William IV, Prince of Orange, at the French chapel in St James's Palace on 14 March 1734. The evening before the wedding, the princess, the rest of the royal family and all their court attended the first performance of "Parnasso in festa", specially composed by Handel for the occasion to an anonymous Italian text, at the King's Theatre in the Haymarket where he was presenting his seasons of Italian operas, and with the same star opera singers who were appearing in his current successful opera ""Arianna in Creta"".
