What measures should I take in my practice to play louder? I play a couple of hours every day whether for a band rehearsal or self practice and generally have not had problems with being able to play with sufficient volume. I play soprano cornet in a couple of brass bands and trumpet in a 5 piece 'function' band (no mics) and don't have any problems being loud enough. However, when I play lead with a big band I find that I have to try and play much louder and that then affects my sound. I have enough range to get the job done in all of the above settings, but this is affected with the big band playing, just the situation where I need to be loud and high.
