Just like \transposition, it transforms music.

Sure.

That does not make all that much sense: transposition works at a time
when contexts are not live or active, so context properties are not
useful generally. They _could_ be used for manipulating the manner in
which _quoted_ music is getting transposed: this happens on-the-fly
during context interpretation.
