I am trying to scan some small music books that played an unknown
fairground organ. The scale seems related to Gavioli or Limonaire.
From the drag marks left by the keys on the book surfaces, the organ
keyframe has 49 keys, spaced 3.5 mm apart.
Just looking over the books, only one of them has holes in the #1
and #49 position. Number 2 position is the bass drum (and cymbal),
#48 is one of the snare drum beaters, the other snare drum beater is
#46. I could not find any book that used the #47 key position between
the snare drum positions.
According to other information, the bass division has 8 keys, the
accompaniment 10 keys and the melody 24 keys. With the music using 42
keys, percussion 3 keys, two unknown margin keys, and the space between
the two snare drum hammers, that still leaves one key unaccounted for
within the span of the book. Often times there was a keyframe cutout
but most often it was furthest to one edge and not a perforation in the
book. Any and all help will be appreciated.
