A musical potty chair comprising a chair member having a central opening in its seat below which a potty receptacle is removably received and wherein a mechanical, electrically-energized music making device plays a tune upon a child first being seated or seating himself upon the chair and thereafter liminating body waste into the potty receptacle, is described. The energizing circuit for the music device has a first normally open-circuited electrical switch mounted in a leg of the chair and adapted to be closed-circuited by the weight of the child sitting on the chair, and a second normally open-circuited electrical switch associated with the potty receptacle when in position below the seat opening and operative to be closed-circuited in response to the added weight of body waste deposited into the potty receptacle to complete the energizing circuit to the music making device and thereby play a rewarding tune.
