Abstract
The embodiment of the invention disclosed herein is directed to a wind instrument made of tubular metal and having an initial straight portion beginning at a mouthpiece receiving end and terminating in a sound-emanating bell portion. The wind instrument is provided with a plurality of piston valves to be manipulated to produce a multitude of different musical notes. A pair of spaced apart tubes is held in a fixed relation relative to one another and to the wind instrument. These tubes have terminating ends extending in a direction opposite that of the mouthpiece receiving end portion. A slide member has a U-shaped end portion which leads into a pair of straight parallel spaced apart portions having open ends fitted over the terminating ends of the tubes and is movable therealong to enable a player to obtain a multitude of different musical notes without manipulation of the piston valves. Lock means is provided between the slide member and the fixed tubes to lock the slide member in a fixed nonmovable position during one instance and to allow release of the slide member for playing of different musical notes during another instance. The sound-emanating bell portion is bent upwardly to allow clearance for movement of the slide member. The mouthpiece receiving end portion is provided with a single slidably adjustable tube portion telescopically inserted therein to provide pitch adjustment for the wind instrument. The singular slidably adjustable tube member is held in a fixed relation by a split-ring clamp associated with the mouthpiece receiving end portion of the wind instrument.
