I do not know this piece, but this might help:

A laughing sound can be made by starting on a high D palm key and playing chromatically down while articulating in note-bending "eeyohwww" fashion on each note (drop your jaw). Do groups of 4 notes down, then start 1/2 step higher and repeat it. You can make a mocking laughing sound.
