How does the narrator describe the character of Calvin Jones?

From the text:

"From his youth, Calvin Jones had moved in a world smelling of cork grease, of ink and resin, of the vague, indefinable odor that clings to the inside of instrument cases. Unmarried and unmarriageable, he walked through life in rumpled frock coats and soiled collars, collecting dust, listening for pitch and key even in the songs of birds and telegraph wires."
