Bound by the inner law which is proclaimed by the first tones every coming tone is prepared.

The whole tone movement points toward the next one.

It is a world of inner self-agreement like that of the colors in a painting, of the curves in a work of sculpture, like the rhythms and rhymes in a stanza.

But beyond the mere self-agreement of the tones and rhythms as such, the musical piece as a whole unveils to us a world of emotion.

Music does not depict the physical nature which fine arts bring to us, nor the social world which literature embraces, but the inner world with its abundance of feelings and excitements.
