Comment #3 on issue 3159 by address@hidden: Rewrite \transposition  
examples in notation manual

Usually, it is a key change that prompts a player to change instruments, so  
the part gets the full key-change notation with a double bar and  
everything. (image, Beethoven Emperor Concerto, German spelling 'B' to  
indicate B-flat clarinet, key changes from concert B to concert E-flat)

When the player needs to change transposition, *not* at a key change in the  
music, there seems to be always something chromatic happening.  The  
examples I found always avoid any indication of key change: no double bar,  
no irritating naturals, and no indication of the current key from the  
viewpoint of the new instrument!  (image, Rachmaninoff Sym 2, also spelling  
in German, the movement is entirely in e minor, the oboe cues are concert  
e-f-cis)  Mahler Symphony 7 does similar things to the first Clarinet.

Another example is Dvorak Sym 9, with horns and Clarinet that change  
transposition without a key-change.

I still suggest the example in just one concert key. We can avoid the  
irritating naturals with printKeyCancellation = ##f
