The process of adaptation
for 43tone organ was :
first, all the reeds
which were originally set
in each cell-board were
removed.
A special tool given by
my piano tuner was used to pull them out.
New reeds were prepared to
be tuned to 43 tone scale.
3 or 4 reeds for each 12 note
are necessary; these can not
be obtained with ease now.
Reeds were tuned by scratching the base of the vibrating flange
to flatten,and scratching the tip of the flange to sharpen.
A small file and a cutter was used.
Thus, new reeds were tuned to 43tone scale and set in the cell board one by one.
Take a look at the photo and you 'll find some marks in pink
above the keyboard. They indicate a C scale in pure temperament.
And some stickersin each color stuck on the keyboard represent
some"Syzygy Chords"which sound very exclusively.
The keyboard is not changed in anyway,and a 43 tone scale
occupies the distance from F2(in YAMAHA term) to the highest F5.
My organ has 61 keys,lowest 3 keys are tuned to C1,F1,G1 for the bass.
There are 2 keys that doesn't work and the rest of12keys are
tuned in 43tone as well.
