You could search the music _expression_ for context modifications.

 

Try running this to see what kind of information would be accessible to you from the music _expression_ you'd be running \naturalizeMusic on:

\displayMusic {

  \key e \major

  cis''1

  \key c \major

  c''1

}

Comparing the output you can see (thankfully) that the 'KeyChangeEvent reflects the transposition:

\displayMusic {

  \transpose c d {

    \key e \major

    cis''1

    \key c \major

    c''1

  }

}

You'd have to make sure that the _expression_ on which you run \naturalizeMusic contains the initial key, though.

HTH,

David
