<DIV>Greetings,</DIV>
<DIV> </DIV>
<DIV> If I finally pick a tuning and proceed, do I tune to A440? The Rollingball website .gif charts illistrate the temperament intervals from C to C. Do I start on middle C? If so, middle C of 523Hz (as in an A-440 tuning), or would I tune middle C lower? Can I still tune an F to F procedure as I am used to for ET? </DIV>
<DIV> </DIV>
<DIV> Also, what does it mean on the side of the Rollingball chart where it states the following sentence: "<EM><U>To zero out total tension change, add this to each offset</U></EM>"....then it gives a number, for example the Valotti has a -1.96 below that sentence. </DIV>
<DIV> </DIV>
<DIV> Also, on the Rollingball chart, the low C-G and E-G is different bps than octave above it. Must I follow that difference through with all the octaves C# to C#, D to D...etc, thereby giving a "stretch" to the whole piano's tuning? if that answer is yes then the whole piano is a temperament itself, and I am not copying octaves as I would do in ET!!!???? Right? Are these temperaments stretched. Woah! I have never done this before.</DIV>
