In LilyPond there is no such thing as "transpose down 4 half-tones".
You transpose from one key to another, not by a distance.

\transpose cis' a will remove 4 sharps, take -4 steps on the circle of
fifths. If you'd rather add 8 steps on the circle of fifths (the
difference implying that the circle isn't actually a closed circle), you
need to write something like \transpose des' a instead.
