You snipped from my reply the following important information:

Keep that in mind, and keep \transposition out of \transpose.  Or the
result will confuse you...

Because they do entirely different things.  \transposition does not
change the visible score, it only makes a difference regarding what you
hear.

\transpose changes both visible and audible notes by the same amount.

At any rate, the documentation is pretty good by now, so try
