"DESH," he said, triggered by her glance, "the Diatonic Elaboration of Static Harmony. Also known as the Major Chord with Descending Bassline. Bach's ‘Air on a G String,’ 1730. Procol Harum's ‘A Whiter Shade of Pale,’ 1967." If she made eye contact now, she'd hear his samples, directionless and at just the right volume. Then more about DESH, and more samples.

He knew everything there was to know about music, and nothing else at all.
