Check out Jussi’s 7400 contest entry, the polonaise machine. It’s a sound generator with the Telemann’s Polonaise tune incorporated into the design.
After about half an hour of brainstorming I came up with the idea of a modern musical box. In a few moments I had the core of the machine ready on a paper and I found a suitable tune; Telemann’s Polonaise. It’s simple, short and has only nine different notes.
