Music where the measure is billions of years long.
Music where the measure is shorter than the shortest period of time the brain can perceive.
Music of different varieties of silence, composed entirely of rests. The rest of anxiety versus the rest of repose, the rest after the cessation of a drum versus the rest in anticipation of a trumpet.
Music which spans an entire life time the first note being the baby’s howl the last the old man’s sigh.
The music of light, of touch, of smell.
Music from languages whose meaning derived entirely from music, the songs therein being a counterpoint of meaning against meaning. Music in contrast which is entirely free of pitch, whose melody derives from the rough texture of words when their literal meaning is subtracted.
The song of emotions not yet felt.
