Small finds a strange looking object in space. He gives it to Mother as a present for her garden – an ornament. But this is more than an ornament as Mother is the first to discover. This ornament can memorise tunes it hears - Mother singing, and the singing flowers, Tiny’s panpiping and even the music trees. And most amazingly, it plays them back together in perfect harmony. And the Clangers have a final surprise when it plays them musical sounds that they have never heard before!
