I've been asked to take a few rehearsals of a local youth bands' beginners group over the next 3 weeks while my brother is on holiday. I'm not Karajan or anything and most of the stuff is dead simple (2/4, 4/4, & one in 6/8). My brother has done this stuff on Sibelius and re-scored the barlines so there are no difficult time changes or corners to keep things straightforward. Do tmp-ers think it would be ok for me to put massive smiley faces on the score to show at a glance which sections are playing so I know where to look? - It might also remind me to smile at the time which hopefully should encourage the players.
