Hi, I'm a high school senior playing lead trumpet for 6 years now, and I'm wanting to get to know the instrument a little better. I have a strad 37 and a bach student cornet, and obviously there are some differences in these instruments, so I'm wondering if anyone with some knowledge of trumpet theory (is that what this qualifies as?) can explain what makes these horns different so I can use this knowledge when, for example, choosing what horn is right for a piece, or maybe purchasing a new horn. (probably a big difference already is that I use a Marc. E14 on the strad and the G6 that came with the cornet. -why is it easier to play a low G below the staff on the cornet? is this simply the depth of the MP? -what makes a cornet's sound darker? -a seem to 'miss' more notes on the strad, as in I blow a little air before I produce a sound. (this could be a attributed between switches between the mouthpieces) There are others but I can't seem to put them into words.
