Several months ago I bought a new Bach Strad trumpet because I was a come back player and wanted a very nice trumpet (I like it and realize some ppl slam the bach strads...) but anyway all I had at the time was a Conn Coronet. I've been taking lessons for the past 7 months and have also started playing with a small brass ensemble from church. I've been thinking about expanding my repertoire of instruments and wondering how people expand and how and why. i.e. now that I have a new trumpet, I almost exclusively play on it and rarely on my old Conn. Also my instructor uses a keyboard/piano to work out rhythms, etc. So I have been jonesing for a new digital piano/keyboard where I can pick up some piano and play back for some accompaniment for my trumpet, but then on the other hand I have thought about maybe the next instrument needs to be a flugel horn or a c-trumpet. A friend and fellow trumpet player in the brass ensemble switches between trumpet and flugel horn all of the time for playing different pieces and they seem like sort of a fun instrument to have. I've heard about often needing a C-trumpet if you are looking at playing with an orchestra and I've been trying to check into local civic band/orchestra to play in as well. Of course this doesn't even get into picking up or ever getting into euphoniums sp? or baritones or other brass. Personally I think I will focus primarily on the trumpet family such as Bb, C, flugel, and the piccolo. Although I have never played a flugel or a piccolo. What have most people done as they progressed in playing and expanding their inventory of instruments? Any issues with practicing / going back and forth between different instruments? i.e. if I start playing a flugel will that mess with my embouchoure for trumpet playing?
