22tET tritones

>>Compare the chords 2 11 18 29 and 0 13 18 29 in 22-tET. The interval
>>18-29 is a half-octave that is pretty dissonant to begin with. Its
>>dissonance is diminshed somewhat by the second chord, which approximates
>>4:6:7:10, but is diminshed more by the first chord, which approximates
>>3:4:5:7.

I hear it!

>>This effect is more pronounced in 22-tET than in 12-tET, even
>>though the latter has the same half-octave interval. I think this is
>>because in 12-tET, the other 7-limit intervals are too out of tune and
>>both chords are quite unstable

Makes sense to me.
