Re: I'm playing 'Prince of Denmark's March' at a wedding in September - I have braces A mentor of mine in high school, my K-6 music teacher, and an accomplished classical organist (seriously - he is fully degreed by the AGO) kept me going in high school when the band program was falling apart by having me play at the church where he served as the music director and organist. It was not unusual for him to hit me with a brand new tune on a Tuesday or Wednesday - something I'd never even heard of, much less played before - and expect it to be ready by Sunday. If I had shied away from everything I couldn't play "now" I would have never played. Sometimes you have to set a goal for yourself. I think that the OP can probably play the Clarke trumpet voluntary - he has posted about some of the ensembles he has played in, and I think it's probably within his capability. I think that he was just looking for some general chops advice and maybe some tips about how to make it sound better.
