Each time the contests come around we all experience the nightmare of errata in parts produced by seemingly reputable publishers. Because we're all human it would be unwise to suggest that any method exists to eliminate errors completely but the number of errors on occasion is unjustifiable. I have a quality control check list taped to my computer - reference letters, articulations, dynamics, instructions to players...etc...etc. - and religiously tick each one off in turn, for all parts. I then have the piece test flown by a good local band. There's often another error somewhere. Beef No. 2: Instructions to players, except dynamics, should be placed above the stave and articulations should generally be opposite the stems except where there are two parts on a stave (for example). Beef No. 3: Some of the notation used in arrangements is baffling. I played a nice piece recently where, despite my 57 years of experience, I just couldn't get the hang of the illogical rhythmic notation used, even after half a dozen run-throughs. As soon as an opportunity arose in the rehearsal I mentally translated the bar into the correct form and I was OK. The rest of the band struggled, too, in case anyone blames it all on my age. Beef No. 4: Can arrangers please put reference letters in a logical place (i.e. at the start of an 8 (or whatever) bar section, not just dump them anywhere? Grrrr!
