In other words: \transpose transposes music. You are right.

I think you mean "\transposition is for displaying pitches only"

I think the great feature you like so much is \transposition, which
lets you input notes in concerty pitch, shows an instrument
transposition correctly, and does not affect MIDI.

Anyway, my point was:

  \transpose <pitch> <pitch> { music ... }

transposes music in { ... } . \transposition works differently. It
does not affect next music expression. It is used the following way:

{ \transposition <pitch>
music ...
\transposition <another pitch> % a change of instrument?
music ...
}

IMO this is very important because commands that affect an expression,
like \transpose<pitch><pitch>{...} does, are catastrophic if you omit
the curly brackets {... }, it would affect the first next expression
encountered, and it could be a single note.
