DESCRIPTION: An antique Miessner Rhyth-O-Phone metronome music player, designed to teach rythm. Features an ebonized wood foundation with internal revolving music playing mechanism. Includes original instruction book. The Rhyth-O-Phone requires the user to punch holes in circular paper discs, the placement and number of holes corresponding to the rhythm desired. The paper disc is placed on the instrument, and a small sickle-like arm is pulled around it by a spring tension mechanism. Whenever the arm reaches one of the holes punched in the paper, a circuit is connected and an electric doorbell makes a sound.
