Trombone 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.
