This is my instrument, it's name is "Little
B." To make it you need three rubber bands, a
small box, a ruler, and a clothespin. First,
you cut two holes in the box. Second, you
stick the ruler in the holes so only a little bit
of the ruler is sticking out on one side.
Then you string the rubber bands on the
ruler. Finally, you put the clothespin on the
top of the part of the ruler that sticks out the
most. My instrument makes lots of different
pitches. To make the pitch higher, you move
the clothespin closer to the box. Little B is
in the string family.
