On the other hand, there is the material that falls outside of the empirical process, the “dark matter” which marks its presence through its “unknownness” but justifies its presence through mysterious and ultimately mystical means. One of my professor’s describes these ideas (klangs, motives,chords, etc.) as “sphinxes”, carriers of hidden knowledge whose secrets remain profound but very much shrouded.
A good composer’s music is wholly intentional- they are able, through mystical processes to make their “sphinxes” feel equally as important as their empirical material. Besides the obvious, some composer that effectively utilized the mystical include J.S. and C.P.E. Bach, Schumann, Sibelius, Prokofiev, Dufay, Mozart.
