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.
Ero e Leandro
"Ero e Leandro" comes from a period very early in Handel's career, when Handel, having travelled to Italy in 1706, was replacing his former Germanic style of composition with the Italian style that he would use for the rest of his life. Music from it would be reused by Handel in his later compositions: Themes taken from this opera appear in both Handel's Recorder Sonata Opus 1, No 2 and in his "Utrecht Te Deum" for the setting of "Vouchsafe, O Lord". In "Agrippina", Agrippina's aria "Non ho che cor amarti" was taken, almost entirely unadapted, from "Se la morte non vorrà".
