Hi Eljakim,

all I can offer you is a function to simplify things a little bit.
However, it is necessary to pass two parameters:
- a destination pitch for transposition and key signature
- a markup for use in the title

% --------------------------------------------------------------------

\version "2.18.2"

exercise =
#(define-music-function (parser location p str) (ly:pitch? markup?)
   #{
     \new GregorianTranscriptionStaff
     \clef treble
     \key $p \major
     \omit Staff.TimeSignature
     \transpose c $p {
       \relative c'
       {
         \mark \markup {"Exercise in" $str "major" }
         c8[ d] e [f]
       }
     }
     \pageBreak

   #})


\score {\exercise c "C" }
\score {\exercise d "D" }
\score {\exercise e "E" }

% --------------------------------------------------------------------

It would be cool to have a function that turns a pitch into a markup, but I
had no luck so far.

You could adapt your function like this:

 % --------------------------------------------------------------------

#(use-modules (scm display-lily))

\version "2.18.2"

exercise =

#(define-music-function (parser location p) (ly:pitch?)

   (let ((str (string-capitalize 

               (symbol->string (note-name->lily-string p parser)))))

     #{

       \new GregorianTranscriptionStaff

       \clef treble

       \key $p \major

       \omit Staff.TimeSignature

       \transpose c $p {

         \relative c'

         {

           \mark \markup {"Exercise in" $str "major" }

           c8[ d] e [f] s2

         }

       }

       \pageBreak

     #}))

\score {\exercise c }

\score {\exercise d }

\score {\exercise e }

% --------------------------------------------------------------------
