Roger Sessions quotes:

What we ask of music, first and last, is that it communicate experience - experience of all kinds, vital and profound at its greatest, amusing or entertaining at another level.

But communication is two-sided - vital and profound communication makes demands also on those who are to receive it... demands in the sense of concentration, of genuine effort to receive what is being communicated.

I have sometimes been told that my music is 'difficult' for the listener.

Music goes deeper than emotion into the energies that animate our psychic life.
