What kind of touch did Chopin have?

Since a description of his touch would require too much space I refer you to the book from which I gathered the most explicit information on this point. It is "The Life of Chopin," by Frederick Niecks (London and New York, Novello, Ewer & Co.), and in the second volume, from page 94 to about 104, you will find what you wish to know, as far as it is possible to convey the charm of one art through the medium of another. Since you seem interested in Chopin I would recommend that you closely study both volumes of this masterly biographical work.
