Robert Schumann said this quote

Without enthusiasm nothing great can be effected in art.

~ Robert Schumann

Think it a vile habit to alter works of good composers, to omit parts of them, or to insert new-fashioned ornaments. This is the greatest insult you can offer to Art.

~ Robert Schumann

You will be most readily cured of vanity or presumption by studying the history of music, and by hearing the master pieces which have been produced at different periods.

~ Robert Schumann

From a pound of iron, that costs little, a thousand watch-springs can be made, whose value becomes prodigious. The pound you have received from the Lord,--use it faithfully.

~ Robert Schumann
