Abstract
A toy musical instrument has a microprocessor which records in memory a plurality of songs. A moveable part of the toy musical instrument is used to open and close a sound switch so that the next note of each song is played with each closing of the sound switch. The length of each note is determined by the length of time that the sound switch is closed, and the interval between notes is determined by the interval between closings of the sound switch.
