Thus there can be an art in architecture. A gifted architect can produce a great deal of beauty in his work. So too with drawing, with embroidery, with the work of dyeing, of sewing. In fact there is nothing which man does which cannot have art in it if he knows how to attune himself to that pitch which enables the art to be expressed. Poetry is an art in the same way. Unless a person is tuned to the proper pitch, he may write poetry all his life and yet it will not please either him or anyone else. So with a painter, or a musician (violin, piano, any instrument); he will not please himself or anyone else during his whole life unless he has become tuned to that pitch.
