When he turned the street corner in chase of music being played so jollily, he took off his hat when his sight fell upon six instruments.  They were lined up on the sidewalk in a crescent profile.  He did look for the musicians, but their faces seemed far too modest behind their instruments to attract notice.  On the other hand, the face of each instrument felt to him most appropriate to the sound made from each.  Each was also taking a significant beating to make sounds from them stir people to feel — what was the feeling that had made him turn the corner? — a little weightless, lightheaded, limber of limb, jumpy…joy.  As if a purpose in life was to wring out of heavy beatings the lighter sensations that stir.  The thought distracted him enough that he had already donned his hat and turned back to the corner before he realized that he was moving on.
