GREEN DAY by Phoenix
How I made my instrument:
traced the shape of a guitar out of 2 pieces of
black Styrofoam. I taped and glued the pieces
together and decorated it. Then I put 6 nails into
the top and bottom. Next, I tied fishing line
to the nails tightening each line differently so
that there were 6 different pitches.
How my instrument makes a sound:
pluck the strings, the strings vibrate and that
makes the sound.
