Extremely minor revelations

Sit down at piano, glance over a litte Bartok children's piece "Study For Left Hand." For some unknown reason, play the left hand's D major chord (just D and its perfect fifth, A; does that even count as a major chord?). For another unknown reason, augment that fifth (A -> A#). Play two bars of 16th notes of each: presto! instant Eminem "Lose Yourself."

Good for 30 seconds of fun, 45 seconds if you add a little water.
