In order to be able to salvage toy pianos that have become damaged during shipping, a structure and process for manufacture of toy pianos has been developed wherein (1) stop piece (or block members) are permanently affixed to certain side forming members, allowing certain other side forming members to be non-permanently affixed thereto via connectors non-permanently anchored to said block members; (2) horizontal slits are provided near the bottom of certain side members to fit over edges of the bottom member, allowing the edges of said bottom member to firmly but non-permanently nest therein; and (3) vertical grooves are provided near ends of certain side members to fit over ends of certain other side members, allowing the ends of said certain other side members to firmly but non-permanently nest therein. These innovations each assist, and together greatly facilitate, the production of a toy piano that is solid and durable in structure while simultaneously allowing easy replacement of damaged parts. Rather than the entire piano needing to be discarded the damage part can simply be removed and a new piece put in its place.
