Acoustic Test

I tapped the corner of my harmonica against an empty ceramic mug on the coffee table. Clink. A sharp, hollow chime bounced off the porcelain. I leaned closer to the rim and blew a low chord straight into the opening. The cup caught the note. Deepened it. Turned a thin pocket buzz into a cavernous, echoing hum, like radio static bouncing across a crater basin. I added a quick tapped beat against the wood with my boot heel. Just checking the room reverb. This mug has solid acoustics.
