Ron K. Said: These are good places to begin your journey, as well as your
ear training to feel the difference of the thirds progression. ?These are
the four strengths that are different enough to make a difference, yet not
too far apart - they make a nice progression. ?
KV 1.15KV 1.3KV 1.7KV 2.1
So the largest offset from ET ranges from 1.12 cents to 2.1 cents. ?It
surprised me how little change in cents could be felt both "from the bench"
as well as from the audience. ?
KV 1.15A 0A# .99B -.57C 1.15C# -.15D .46D# .69E -.46F 1.15F# -.31G .76G#
.31Major thirds 12.1-15.0 ? ET thirds = 13.7?
KV1.3A 0A# 1.13B -.65C 1.3C# -.17D .52D# .78E -.52F 1.3F# -.35G .87G#
.35Major thirds 11.9-15.2
KV 1.7A 0A# 1.48B -.85C 1.7C# -.22D .68D# 1.02E -.68F 1.7F# -.46G 1.14G#
.46Major thirds 11.3-15.6
KV 2.1A 0A# 1.82B -1.05C 2.1C# -.28D .84D# 1.26E -.84F 2.1F# -.56G 1.4G#
.56Major thirds 10.7-16.1
There are stronger choices, but these offer a 'safe' place to begin a
temperament journey..."

Ron,
Hmmm? One slight problem, as I see it, most ETDs only go to ONE Decimal
point, not two. I'll have to use my SOT, Modified with Bournes Ten Turn
Pots, to lay those in. Seems like there is a need for that extra decimal
point Someone should maybe tell the ETD manufacturers??? Thanks for the
info. I'll give em' a try on my German Overdamper thang.<G>
Regards,
Joe
