Demonstrate a pretty drum.
This is an Ashiko drum, apparently similar to that pictured with Feynman. Unfortunately or fortunately, as the case may be, this one has a synthetic head. This drumhead is nicely tuned to its resonant cavity. For comparison, we have a beat-up steam-damaged older drum with a compromised resonant cavity, so it does not have as nice a tone.
