This is an instrument everybody can play. You play Marbles by placing the marbles on the board. The higher rows are the higher notes and the lower rows are the low notes. The instrument loops over columns and if there are marbles in a column it plays the notes (like a barrel organ). When a note is played the board lights up around the marble, so you know which note is played. It can never sound bad because all notes are in harmony. It’s a tool to express yourself through music, even when you can’t play a conventional instrument. For this project I made a working model. In order for me to test it. I tested it with Neo and he was very enthusiast. It was interesting to see how different a child plays with it. He was way more visual in his approach making musical patterns with the marbles.
