I'm not a fan of parts passing, please hear me out on this one. I tend to think that the arrangers have arranged the parts so that balance can be obtained and that in the majority of cases if there isn't balance it's because some players are not blowing enough/some players playing too loud rather than the parts themselves being badly arranged. Parts-passing in my opinion should only occur as a last resort. When a player has tried for weeks to play a part but can't pull it off then I think it's fine for the part to be passed to someone who can. Otherwise, I feel it destroys the self-confidence and motivation of e.g. backrow cornet players if some of their more tricky parts always get passed to front row without them having a proper go at it. Additionally, you will then have front row players playing without much rest which is not a good idea anyway. I would be interested to know your opinions on this issue. Also, what do you make of part passing from one instrument to another- I tend to think this is not a good idea in the majority of cases and surely a good judge would be able to hear this 'cheating' going on! Part passing is one reason I think open adjudication would be welcomed, as conductors then might be less keen to pass parts if they felt the adjudicator's eyes was on the band!
