Well, only if you regard a note as a first class object (I dont).

(1/12)/note makes more sense because theres /is/ someting very 12ey about
12tET notes (the clues in the name ;), whereas there is nothing 12ey about
octaves. At all.

Just for the record I do think that having a note representation in the
API is wrong, but I'm letting it slide. I guess I'l never write any code
to support it anyway.
