The Gebr. Bruder Model 107 Fairground organ is a 52 keyless instrument. It features 5 bass notes utilizing flutes and low trumpets; 10 accompaniment and 22 melody notes of flutes, violins, and principals; a countermelody produced by 14 trumpets. These sections are played individually, at either piano or forte level, all controlled automatically by the music roll, giving the instrument great dynamics. Also included are a number of percussive effects including: bass drum, cymbal, snare drum, crash cymbal, castanets, triangle, and xylophone. These, along with the 179 pipes, help produce some the happiest music on earth.
This Airophon was built around 1925, and was the first to use roll music, all previous used book. This is the deluxe version, which plays a drum roll cadence during rewind, using small pinned cylinder, a glockenspiel, and a crash cymbal. The latter two are played by the addition of two more holes in the music, holes #0 and #53. This allows it to play standard 52 hole music.
