@note The fidelity of the notes is poor due to jitter
produced by the display task.
@note The tunes are stored in RAM. Adding more tunes can cause
a subtle memory overflow and the program will fail. A solution
would be to store the tunes in flash memory but this requires
some jiggery-pokery due to the Harvard architecture of the AVR.
