Comments: This score is partly a spartito, as the words are marked above the musical part (of the piano).
Also, the introductions of the instruments are marked, while in some places the voices of the orchestra (melodic lines) are so marked that we have a "condensation" for piano that in a way replaces the orchestral score.
Where the notes cannot be played (by the piano) they are marked fainter and in a smaller size than the others.
