The Rotary Valve Trumpet is common in Germany, and lots of companies make these instruments. The advantage of a Rotary Trumpet for beginners is that you don't need quite as much air to make a good sound on it, plus the Rotary Valves allow you to play with precision. The neat thing about a Rotary Valve Trumpet is that it takes a Standard Trumpet mouthpiece, but it has a Slightly mellower sound than a Standard Piston Valve Trumpet so it won't overpower other instruments.

I have recently fallen in love with rotary. Would love a Schargel Berlin Heavy, but in lieu, I had to settle for cheap Chinese - but its good enough. You might find this review of use or interest. Cheers and thanks for the inspiration. kzfaq.info/get/bejne/jriYlseQuZnPiXU.html
