This is why so much of today's contemporary music is SOOOOOO bad in terms of its overall deficiency as composers exhibit a general carelessness in crafting melodic lines. Much of it spreads more than an octave, often goes way too high in pitch, demands acrobatic gymnastics by including unusual intervals (6ths, 7ths, and worse), contains syncopated upbeats and more...
...and say that CMAA seems to be a response to the problem that, on the contrary, everybody seems to be singing the stuff.
But I perhaps mistake the point, which could be aimed instead at Ligeti or maybe even Mozart's tenths and twelfths. I hope it would never occur to anyone to have a congregation sing these last two, but neither one seems to be having much trouble attracting appreciative acrobats.
