Ok...I have a Bach Bb and a Courtois flugelhorn. I play mostly contemporary praise and worship at my church, and I love jazz and classical. My problem is this.......I am wanting to expand my "sound" a little more but I realized I didn't know the differences in the other horns. I'm embarrassed to say that I don't even know the use or purpose of a C trumpet, much less a G, or a D/Eb compared to a Bb Trumpet. I know that they are in said keys, but is there a noticable difference in sound, or playability? Can someone break it down for me? Also, explain the sound of the cornet compared to the Bb. Thanks.
