A melodic candle assembly having a generally cylindrical wax body seated in the top of a tubular base. The wax body has an axial wick. Adjacent the wick is a thermoresponsive member comprising a thin piezoelectric strip with metal films on opposite sides thereof which serve as electrodes. An electronic circuit in the base has an integrated circuit comprising a memory stage containing prerecorded signals representing audible sounds. A loudspeaker in circuit with the memory stage reproduces the audible sounds when activated. The thermoresponsive member is connected to the electronic circuit and applies thereto a piezoelectrically generated voltage when the candle is ignited to thereby trigger the memory stage and activate the loudspeaker. When the candle flame is extinguished, the audible sounds are stopped.
