How to Make It

By using brass tubes, or better, tubes made of bell metal, you can have a xylophone of another order. Use tubing 3/4 inch in diameter and have the first one 5 inches long for the fundamental.

Keep on sawing them off and filing them down until you have them all done and all in tune. Make a wooden frame of 1/2 inch stuff and have the bottom 2 inches wide at one end, 4 inches wide at the other end and 17 inches long.

Saw off two strips of wood 1/2 an inch thick, 1 inch wide and 17 inches long. Bore fifteen 3/4 inch holes 1 inch apart measured from their centers in them; glue a strip of felt or thick cloth to the wood in each one and slip the tubes in the felt lined holes as shown in Fig. 112.

How to Play the Tubaphone

To play this peculiar instrument use a couple of felt covered mallets; these can be made by winding a little ball of string around one end of each stick which should be about 1/4 inch in diameter and 8 inches long, and then covering it with felt. Beat the tubes with the felt mallets in exactly the same way you do when you play the xylophone.
