I recently purchased a P-Bone. Partly for the novelty and partly because I have been wanting to learn to play trombone for a while. Tonight I started working on the trombone a little. Learning positions and how to read bass cleff. My question is for anyone that has had success with being proficient on both instruments. When I lay the trombone down and pick up the trumpet if feels a little weird and my tone doesn't seem to be as full before playing the trombone. What are some good ways to be able to switch between instruments without losing ground on the trumpet? Is there anything that should be avoided? I want to learn both but not mess up my trumpet playing. I think it would be fun to double in the big band on the same tune for solos.
