Piccolo Trombone

This was designed to use a piece of 1/2in PVC pipe as the outer slide, making the instrument more airtight and playable. All parts fit into each other without glue needed, if they do not fit use hot water to make plastic malleable The diagram shows where all the parts go/ how to assemble Has around 6 slide positions, takes a standard trumpet mouthpiece, roughly in the key of high Bb
