Well... I guess one important element in the tiling/sequencing issue
(forgive me for my lack of the exact mathematical knowledge) is
time-domain. Much of Music and it's drama, versus for instance painting,
is time: suspense, arousal/relaxation etc. have to do with time. So if
you take a piece which are the 'tiles'? Measures? themes of the 'sonata'
form? Simply recurring elements?
So if on the one hand many academics disregard 'quality' composition as
a mere juxtaposition of cool sounding melodies or progressions, on the
other hand it's true that the time-domain calls for some sort of tiling
in the sense that something comes after something

Ok but the fact that people used mathematical relationships without
being fully aware of them (e.g. I IV V I progression) doesn't mean the
relationships don't exist or aren't important. The whole 'western' tonal
system is heavily dependent on this 'maths' we like it or not :)

Being (as I said) a musician and not a mathematician I have to say that
I don't like much this kind of maths=boring=kills the fun etc. When I
started studying electronic music and also some of the physics and maths
behind it I was clearly fascinated to learn some of the things behind
music, and I still have great fun making it.. but of course that's me :)
