It's a fun little instrument to practice with, I might even bring it for a gig. The valves feel really nice. I can't say much about the sound or tone as I'm not really a brass player.
Playing the basic C Major/Minor scale goes just fine, but I find it a bit hard to go above and below that, I need to push a lot more air through it to go higher. I've been told that it's normal for it to be a little harder to play than a regular trumpet. Luckily most music I play is within the C Major/Minor scale range! An added benefit of practicing on this pocket trumpet is that playing a full sized instrument later on feels so much easier in comparison.
Purchased because I'm a woodwind player and all my friends are brass players so I wanted to join the club. Of course I had to get it in black to match my clarinet.
