Yes, if they are exactly in tune, which in orchestra playing can be extremley tricky. That is why orchestras would rather hire a trumpeter with an extremely huge presence to his tone, and have a single tone to deal vs 2 trumpeters. Yes more trumpets would augment the volume in therory, but they also have a canceling out affect when not played exactly in tune. In our classical orchestra, even though we use only 33 players, we have an unusually huge sound due to the high quality of players. The overall affect still likens it to the piano. Play a piano out of tune vs. play in very good tune. The well tuned piano is going to be much more volumous due to the reinforcement of harmonious tuning. This is a fascinating topic with complexities galore. I would love to this thread to thread explored to the outer limits. Tom Servinsky,RPT > I'm talking strictly about volume.
