You were right, it was cute, although as with most “let’s talk about the MATH” videos, its philosophical underpinnings seemed … lacking. After all, no one would argue that 12TET is the ‘default system’ in Western music because it is an optimal tuning for expressing 5ths, much less the intervals found in the major scale, so it’s not clear to me that 7-TET or 19-TET would be “better”.
One exciting (or not) thing about being a musician in the 21st century is that in fact, if one decides, it’s dramatically cheaper than in previous centuries to create strange, “bespoke” pitch systems for one or a few pieces, since harmony need not play the same organizational role it has in music of the past.
