A Resonance Test

I trotted over to the corner where the big wooden guitar rests on its metal stand. Up near the bottom curve of the body, a plastic guitar pick was wedged right between two brass strings! I hopped up, gripped the smooth triangle with both hands, and gave a brisk tug. Twang! The thick lowest string hummed a deep, rolling note that vibrated straight through my palms and into the wooden floor. I leaned in close, tapping the hollow wood with my knuckles to hear that rich, booming echo fade into the quiet room.
