The LPNR:
The pitch to use for \transposition should correspond to the real sound heard
when a c' written on the staff is played by the transposing instrument. This
pitch is entered in absolute mode, so an instrument that produces a real sound
which is one tone higher than the printed music should use \transposition d'.
\transposition should only be used if the pitches are not being entered in
concert pitch.

Would be more explicit: transposition can be understood as the act of
transposing, whereas \transpose exists too.

I did various attempts at that, but was unsuccessful.

I extracted the first two measures so that the phenomenon is clear, sorry if
that’s a bit long.
Comment the line :
