Orchestral music is in what microtonalists call adaptive 5-limit Just 
Intonation; Hindemith calls it the natural tuning. A measurement of a 
performance of a string quartet that should have been (atonal) E12 showed that 
it in reality it was in something like Pythagorean. There are not references 
for playing in E12, unless there are som such instruments added, and using 
would make the harmonies sound less focused.

A composer should write so that it becomes easy for the musician to perform, 
otherwise they will have to edit the score, which costs time and money. The 
musicians then listens to the other musicians and adapt so it sounds right—this 
is what one of my flute teachers said, who sits in an opera here. Or modern 
composers just haven't checked it out. Some do, though.
