Bob and Christine Play the Glaviphone

Since Christine had not seen Bob's franken-horn, the glaviphone was brought out for a demonstration. For those not in the know, the glaviphone is something that Bob bodged together while learning to become the brass musical instrument repair specialist that he is today. As you can see, it is an odd assortment of tubing with two mouthpieces, a french horn bell, a trumpet bell, and some valves to allow selection of which bell(s) are to be used. After Bob demonstrated its....ummm...range, Christine joined in. The sound produced was truly awful, but very interesting.
