On second thoughts, it seems like transposition constraints for the
whole of LP could be set by four naturalize-limits: upper and lower
limits respectively for c, e, f, b; and upper and lower limits for
everything else.

so

    (naturalize-limit > 1)
    (naturalize-limit < -1)
    (naturalize-limit > (/ 1 2))
    (naturalize-limit < (/ -1 2))

should cover regular tonal transposition; make it >= and <= to get my
naturalizeMusic function.
