Hi all, rubbish title and equally not a great question but here goes... I am having to work away pretty often at present and I am wondering if I get a plastic or pocket trumpet would this be ok to practice on. I play the cornet in brass bands and play trumpet on occasion in a community orchestra however want something small and or light to practice while away which is not one of my regular heavy expensive instruments. I have recently had a play on a plastic tromba trumpet and it required a different play style but the principles were the same. I wondered if practicing on one of these would be a good thing or not. I am not confident that practicing on an instrument which I don't normally play on is a good thing. I know I am rambling on but hope you get the idea of what I am asking. Thanks all.
