Go to as many live performances as possible. (not just trumpet stuff either) Thats one thing I wish I did in high school. Its fun and you can really learn. Try talking to the musicians. But, it seems like you have a passion for music wich is great!!!! You should check out these sites...... "trumpet-stuff.com" and "erikveldkamp.com" THey are really cool. Erik's site has some solo transcriptions lots of other cool stuff. But click on "trumpet kings" on his main page for alot of aewsome video clips. Also, JoJo, hymnals are a great thing to use for learning transposition. Just transpose one or two short hymns out of it a day and you will be doing it quickly in no time. Plus they can get your chops burrnin'. I found that transposition for me is just a matter of doing it on a regular bassis. goodluck ytr-6335S.
