My 6 year old is very interested in the trumpet. The first time he put it to his lips he was able to play some notes and I'd like to encourage him. That said, I'm scared he'll use my shiny new horn as a light-saber if I let him hold it on his own, plus it's still kinda big for him. So considering used cornets, or maybe even a cheap pocket trumpet, as easier to hold. I've never tried a pocket trumpet; putting aside quality of the sound, would ability to generate notes on a regular trumpet translate to approximately the same result on a pocket trumpet? Or do they take more lung-power? Just want something he can toot on for a few months until it's clear if he's actually interested in taking lessons, and won't make me cry if he bangs it up a bit in the meantime.
