I know many of you are familiar with the piano tuning program Tunelab. For a quick study of visualizing the interactions between the different types of tuning octaves on two pianos, see:

Outstanding!
Thank you Jason!!! (and Ron)
I will certainly use this to my aid when using Tunelab on future tunings.

Those graphs are very interesting to study. Does Tunelab create these graphs? I looked and cannot find this.

I can see on the tuning curve screen the result of selecting the various combinations, but can't create a similar graph to those above?

Thanks,
David

No, Jason's a spreadsheet wiz...

Okay, I see how he did this. Basically, let Tunelab create an auto stretch for a particular scheme, say 6:3 and 4:1.

Then, without re-clicking the "auto" functions, select a different tuning scheme, and it will show what Jason is showing on his examples.

You have to cycle through each scenario manually, and compare. Jason has taken each of these and plotted them all on the same graph.

Still very interesting!

Thanks,
David
