34 Studies The famous Brandt 34 Studies (originally for trumpet) are now available for tuba. These brilliant studies are among the best for developing a solid bravura-style technique. Emphasis on exact rhythm, precise multiple-tonguing and flexible technique make this book important to tubists. Many of these studies are based on passages from famous orchestral works such as the Ride of the Valkyries (and others). Most studies can be performed on both low and high tubas. Spiral bound.
