Mechanical Music
Advertising space is available in our bi-monthly journal, Mechanical Music.
The Musical Box Society International (MBSI) is a group of worldwide enthusiasts for automated musical machines whose origin predates electrically-amplified music. We are intrigued by musical instruments which play themselves using punched paper, punched discs, pinned cylinders, paper rolls, or Musical Instrument Digital Interface (MIDI) and are powered by hand crank, springs or electric motors.
