I've been to a few band rehearsals in my time and one of the main things that really makes me enjoy a rehearsal is when a conductor allows the band to play the music through from top to bottom, as well as efficiently rehearsing the music. On the opposite side of that, I find it quite frustrating when a conductor stops a lot. By this I mean you might start playing, then after two bars the conductor stops you all to mention a minor detail to be improved. The conductor starts the bars again, then stops again to mention another small detail to change. This can happen maybe ten or eleven times!! An entire rehearsal can be spent in this (IMO) unproductive frustrating way. It really irks me. A conductor should allow the band to play and stop fewer times and mention the things s/he wants changing all at once. At which point pencils should of course start scribbling away to write down the conductor's instructions. Plus a lot of things can be indicated whilst the band is playing i.e. louder, quieter and the way they hold themselves in front of the band to indicate style etc. I conduct a junior band and I ALWAYS play things through, select a few bits to work on and then put it together at the end. It really helps them because a lot of the time at ANY level, just going through it can help people figure out a lot themselves. Plus the extra blowing really makes a difference. So to all conductors out there, let us play!! It really helps! Anyone else?
