My mate is conducting hill orchestra at uni this year. he asked me to join playing trumpet, i said sure, good chance to see him and to play me trumpet. so, then he asks me to play the french horn for a couple of pieces parts on my flugel. i say sure, ill take a four hour round trip home to pick up an instrument, then transpose a load of music and play those, and play my trumpet for other parts of the concert. then he says can anyone play the timps, and he looked so stressed that i say yeah sure, i played then for two weeks last year, so now im playing those for a piece as well. im playing three different instruments in one concert. excellent. any tips on timp playing anyone? im ok with playing most stuff, but not an excellent roller and not too good at changing notes and playing at the same time. any help would be much appreciated.
