SV: The JC ET part 1

[Ola Andersson]

Hi Richard

Yes but different pianos gives different beat speeds.
I know it's possible to tune the F3-A3-C#4-F4 contigues to start with
but I found it easier to do what Jim Coleman taught me and tune the A3-C#4 first with help of tuning those thirds equal beating with the F3 and F4 2bps flat. after finding the A3-C#4 I tune the F3-A3-C#4-F4-A4 contigues. Try it. It's fun. Please give me a response on that.

Yours

Ola Andersson
