'Mozart' will do it for you too.
But maybe she just needs a guitar chord chart sitting beside her as a prompt.
I've taught a collegue the chords for various songs and he always pauses when I say F#minor or C# or Bminor etc so on his copy of the songs I've quickly drawn a little box with the chord shapes and he's happy. He knows all the straight forward basic chords and can play anything in A or D or G but now he's good in E or B..... as long as he has a prompt for the tricky chords.
