I decided to make music for my grandma using a wooden box with a hole in it. Steel wires, or strings, stretched tightly over the hole vibrate and make noise which is amplified by the body of the instrument. A stick attached to the box allows the player to shorten the length of the strings by pressing them down, which changes the note that they produce. A piece of plastic shaped like a rounded triangle can be used to make the strings vibrate. This “pick” can be held in one hand while the other hand is used to shorten the strings, this technique allows the player to make chords as well as individual notes. The metal wires can also be stretched over a magnet, which is attached to a speaker, this causes the sound of the instrument to be amplified through the speaker instead of the body of the instrument. Different sounds can be produced with different electronic modifications to the instrument or the speaker.
