Music is an incomparably more powerful means and is a subtler language for expressing the thousand different moments of the soul's moods.
How can one express the indefinable sensations that one experiences while writing an instrumental composition that has no definite subject? It is a purely lyrical process. It is a musical confession of the soul, which unburdens itself through sounds just as a lyric poet expresses himself through poetry...As the poet Heine said, 'Where words leave off, music begins.'
I have put my whole soul into this work [The Pathetique Symphony] . . . You cannot imagine what joy I feel at the thought that my days are not yet over and that I may still accomplish much.
