"The field open to the musician is not a miserable keyboard of seven notes, but an
immeasurable keyboard still almost entirely unknown on which, here and there only,
separated by shadows thick and unexplored, a few of the millions of keys of tenderness,
of passion, of courage, of serenity which compose it, each as different from the others
as one universe from another universe, have been found by a few great artists who do
us the service, by awakening in us something corresponding to the theme they have
discovered, of showing us what richness, what variety, is hidden unbeknowst to us within
that great unpenetrated and disheartening darkness of our soul which we take for
emptiness and nothingness."
- Marcel Proust
