Re: [tuning] Digest Number 2225

Joe et al. I believe Groven's tuning the same as the 1/8-th Skhisma
tuning discoverd by Helmholtz. See Ellis's appendices in "On the
Sensations of Tone."

One might also compare this tuning to Sabat-Garibaldi's 1/9-skhisma
tuning which makes the 6/5 and 5/3 just rather than the 5/4 and 8/5. See
S-B Dinarra web pages for details and the Dinarra itself, a guitar
fretted to 53 tone of the 1/9 skhisma tuning.
