Ab in the chord of Eb? What's that all about then? I noticed this a while ago, and have raised it at rehearsals, and my conductor suggested it's meant to be an Eb. Makes sense, but the thing is that the misprint (assuming of course that it is one) is on both editions I've played (i.e. both on an original part with the G trombone positions marked in [!], and the new edition) and both scores. Any suggestions anybody?
