How to improvise on trumpet with a rock band?

I have played trumpet for 6 or 7 years and know all the major scales. I also play guitar in a band and want to play trumpet when we just jam sometimes. How would i transpose with the trumpet? For example, if we are jamming in E, what key should i play in for trumpet?





Also if anyone does play trumpet in a rock band, are there other scales better than major to improvise in? Is there a site to learn them?





Thanks

How to improvise on trumpet with a rock band?
If the band is in E, you should be playing in F#. Whatever key they are in, you will play 1 step higher.





A blues scale is pretty useful for rock jamming - in C it would be C-Eb-F-Gb-Bb


The bluesy notes would be E to Eb and Gb to G - as grace notes.





Good luck.
Reply:Your trumpet is probably a Bb trumpet, which means that your C is actually a concert "Bb". Therefore, you need to play in a key 1 whole-step higher than the one being requested. You would do this by removing 2 flats from the key signature, or adding 2 sharps, depending upon the key. So for E, you would be playing in F#. Eb would be F, F would be G, etc. HTH.
Reply:There is a band here in Maryland called Lennex. Check em out on MySpace. The singer is an accomplished trumpet player and incorporates the trumpet in the bands sound. That should give you some ideas.
Reply:agreeing with fishstory I think you should play F#


(I play trumpet myself but not in a band)
