Composer: G. F. Handel
The Air from Handel's Water Music is the 5th movement in a suite of pieces composed (along with two other complete suites) for England's King George I in 1717. George had commissioned the music for a concert meant to be performed while he and a group of friends traveled together down the River Thames after a party. The concert actually began after midnight, and it was said that King George loved the music so much, he had the musicians play through all three suites 3 times!
The Air itself is wonderfully suitable for wedding processional music, lending itself to a stately walking pace. It is typically performed by strings, as it would have been in the original concert on the water.
