Those notes that sound wrong were corrected in the Salzedo edition. Thank you for the corrections; now I’ll have to re-learn the piece. It does sound better. I think, if it is extremely well-played, the tremolo effect in the opening does work as written; it points toward the bisbigliandos later on. I rather prefer the piece as written wherever possible. Pierne had a terrific ear. I believe this is the contest piece with which Salzedo won his premier prix in harp.
