In proofing by playback, there was one note which (isn't this funny, really?) was either a Tallis-esque crunchy cross-relation, or it was a mistake I plugged in while executing the by-sight transpositions in which the process of arranging this Intermezzo was rich. In principle, I might have kept it, even if a mistake . . .
But when I found the correction, the music as originally composed struck me as clearly superior.
