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.
Well, yeah, that _might_ be seen as a little misleading.
Certainly, that statement is supposed to say: It does not make
sense to use \transposition for concert-pitch music.
But using \transpose a c'
\some_concert_pitch_music_for_oboe_damore in effect creates music
_not_ in concert pitch, for which then \transposition can (and
should) be used, like in the example I gave earlier.
