I do not flatter myself that so numerous an assemblage has come here this evening to listen to me, for it is much more likely that' you have foregathered to hear Mr. Arthur Alexander play some of Scriabin's remarkable music. I cannot—at any rate this evening—enter into a full discussion of Scriabin's music and aims, as our present subject is concerned with the harmonic method of Scriabin rather than with his actual music.
