The Jo-Ral 3510 Trumpet Short Cut is an innovative new helper to the brass player.The Jo-Ral short cut allows you to do warmups, slurs and tonguing without using your trumpet. It is excellent for extending practice time, improving embouchure, and as a lip builder.The Short Cut is a piece of copper tubing with 2 holes, a ventura at the top and a bell-shape at the bottom. A mouthpiece can be inserted into the ventura. The "Short Cut" is comparable to the natural instrument. At 5-1/2" it is small enough to take with you anywhere.
