One of eight handcrafted wooden choir dolls released by Teenage Engineering designed to perform choral arrangements and original compositions via MIDI over Bluetooth, each made from solid beech and finished with hard wax oil. Inside every doll is a removable speaker module that doubles as the CPU and BLE transmitter, delivering up to four hours of rechargeable performance. Their built-in melodic algorithm uses counterpoint composition to generate layered harmonies, while motion sensors allow playful physical control through tapping, tilting, or movement. Each doll has a distinct vocal character, and when grouped together they automatically connect and form a responsive ensemble, blending into a dynamic choir that can be conducted wirelessly using compatible MIDI controllers.
