Abstract: The embodiment of the invention disclosed herein is directed to a novel tenor trombone construction. The tenor trombone is capable of performing as a standard slide trombone and/or as a piston valve trombone. The trombone can be operated in these two modes simultaneously or individually. The piston valves can be manipulated by the left hand of the user while the slide member can be manipulated by the right hand, without requiring the player to remove either hand from its normal playing position, or from interrupting his hold on the instrument while playing. The piston valves are so positioned as to enable the user to operate the piston valves with the right hand. Holder means is provided for the slide member assembly to hold it in place when the piston valves are being manipulated by the right hand.
