Your final solution yields no sound, throws an error message, AND hangs
the kernel at my machine:
notes = Table[N[(440/64)*2^((n + 3)/12)], {n, 60, 72, 1}];
Sound[Play[Evaluate[Sin[# 2 Pi t]] & /@ notes, {t, 0, .5}]]

Your Manipulate DOES work, on the other hand. (As far as I can tell, since
I don't know what it's supposed to sound like.)
