RE: [tuning] Re: high third sound examples

Graham, although it's true that Jerry's voice fluctuates quite a bit, it
does spend most of its time within a very narrow range. Is it possible to
get some sort of histogram out of "Spectrogram"?

For each frequency bin, you can get it to color according to the
intensity. And with enough points in the transforms, you can see the
peak. That means, as near as I can tell, the low third is at 6:5.
There's still a few cents variation.

The high third example has a less clear peak. And when the pitch is
relatively steady, it isn't always at the same point. The variation is
between 6:5 and the 400 cents from one such region to another. These are
only quick calculations: it only ranges over two or three divisions.

I sincerely hope you mean 5:4 and not 6:5 in the preceding two paragraphs.
Otherwise, your spectrogram might need an encephalogram :)

Thanks for doing the histogram, though!

Anyway, it sure seems like you're saying Jerry was able to "lock" the low
third much more accurately than he was the high third. A few cents variation
around 5:4 is really the best you could hope for from a human vocalist.

Come again?
