A hundred or more guitars hung high on the wall like a choir holding a silent note in unison, mouths forming perfect O’s as if waiting for a nameless conductor to snuff the note with a tight fist. Of all the guitars displayed, I really only saw one: a Washburn acoustic, stained a dark greenish-blue, nearly aquamarine; colors I would one day recognize in the deepest shores of Puerto Rico at high noon. The guitar was oceanic in its own way, emitting a rich, lingering tone from within, like the low, throaty moans of deep-sea geologic forces.
