[Harp-L] Spiral-Chromatic re-tuned from 10-hole chromonica

[Robert Hale <robert@xxxxxxxxxxxxxx>]

Success!

My most ambitious re-tuning project to date -
Chromonica 10-hole in C  is now a D Spiral-Chromatic.

It is 40 reeds instead of 20. It's valved, so getting to both sides of the
reed is not practical.

   1. Identify stock tuning of Chromonica, C blow-draw upper plate,  C#
   blow-draw lower plate
   2. Use Jim's Tune-O-Matic online to choose new notes for spiral
   http://www.truechromatic.com/tune-o-matic.php
   3. See intervals to be changed (maximum -5 semitones with solder, Max +1
   semitone by thinning the tip)
   4. Sand off 2 different color coats of enamel applied by previous owner
   5. Old English furniture oil with walnut stain on the comb
   6. Original plate pins replaced with drill, tap, and threaded bolts.

Jim's TRUE CHROMATIC (SPTCHR00) shows 3 notes not consistent with the
spiral, no doubt for the player's preference. I chose to return those 3
notes to the usual spiral pattern.

Whereas the 10-hole diatonic Spiral gets 9 of 12 chromatic tones per
octave, this Chromatic-Spiral has is all. The few redundant tones means
alternate patterns are available for soloing.

I didn't spoil any reeds in the process, so I'm feeling about 10-feet tall
right now, and probably bullet-proof. (I am enjoying it temporarily,
because life will probably take me down a notch soon enough.)
