Barely tongue-in-cheek:

absolute =
#(define-music-function (parser location music) (ly:music?)
   (make-music 'TransposedMusic 'element music))

When placed inside of a \relative block, \relative will route around
this music.  It stays in absolute pitch and does not even touch the
reference pitch of \relative.  This might be somewhat useful in
connection with music variables:

melody = \absolute { c'4 e' g' c' }

\relative f { c''4. g'8 c,2 \melody d4 e f c }


If you wrote just

melody = { c'4 e' g' c' }

here, things would go rather haywire.
