The candle has a wick that contains an optical guide, such as a fiber optic cable. An electronic circuit is coupled to the optical guide so that when an optical signal is received by the circuit, it plays a musical tune. For example, the optical guide can be coupled to an optical switch, so that the optical signal produced by the flame will close the switch and complete a circuit. The circuit can include a storage device, such as an IC CHIP, to store a musical tune. This tune is then played when the candle is lit. When the flame is extinguished, the burnt wick will prevent ambient light from activating the circuit.
