Huh? I thought the first series was 4:5:6. That's why I suggested we put the
third on top. It's simply easier to hear that way. As far as I'm concerned,
the effect was equally evident in jerry0 and jerry00.

I suspect that perception of the illusion depends upon having considerable
exposure to JI performance. I realize that this idea doesn't seem to jibe
with my observation that the effect occurs with novices, but then some of my
"novices" may have done significant group singing before they came to me.

Therefore, I'm not sure the tuning list is the best place to get a sampling
of who does and who doesn't hear the illusion. What do you think? I'm
curious about Joe's experience with JI performance. Any singing or string
playing, Joe?

Nope. Just let the chips fall where they will.

jerry0 was simply a 4:5:6 triad, all notes on together, all notes off
together. so the effect, as far as it relates to any actual direct
comparison of perceived pitches, cannot be tested through jerry0.
