Dave,

I published this method in 1988 in the my "Stopper tuning - Equal =
temeperament based on pure duodecimos (12ths)" in the 3/1988 issue of =
the euro piano (european piano association magazine) about P12 tuning.

regards,

Bernhard Stopper

sounded so good, or in tune.  Very rewarding stuff, great technique.  =20
