Because it's so close to that -- two of the notes are 50 cents off, and
three of the notes are already there.

Well, not according to dualistic theories like Partch's. But since our
central pitch processor tend to fit things into harmonic series and not
subharmonic series, you tend to hear the chord in terms of the former -- as
a dissonant version of 4:5:6:7:9.

Exactly:

9/8-------9/8
9/5-(50¢)-7/4
3/2-------3/2
9/7-(50¢)-5/4
1/1-------1/1

Do you hear it in the sine wave example? I sure don't.

I'll reserve comment until I'm sure whether you were referring to the sine
wave example or the sawtooth example (Joseph?)
