That means you have notation that is in pitch, and you want it to look a
fifth higher.

Should be perfect.  Can you show what problem you had here?

Looks equivalent (assuming English note language where bf is b flat).

\transpose transposes everything completely, Midi and score.  So the
Midi is a fifth too high.

There is a Midi-only command for _then_ telling LilyPond that the
instrument is transposed.  So you need to place your horn part within

\transpose f c' { \transposition f ... }

in order to have the visuals go up one fifth, and have the Midi
compensate for that.
