Handel's Water Music suite no. 1 starts with a slow overture with 1/16 notes at the middle and end of each measure:
Some performances play it "as written" [Koopman], but some play the 1/16 notes delayed and shorter (something like 1/32) [Gardiner, Harnoncourt, Savall]. I don't recall shortening the 1/16s as a common baroque practice. Are there any performance instructions, historical notes or research as to why they can be played this way, and is this considered the historically informed way?
