[MD] ZAMM resonances (no mention, but still ...)

[Michael R. Brown]

Romantic, then Classic:

“The thing is, I've been working on pianos so much, I look at a piano 
and can tell if something is wrong, out of place. You know, because you 
see the piano every day, you know that something's out of place, you can 
tell right away.”

What Boot hears in a piano comes from 52 years of experience. He’s 
learned the ins and outs of piano acoustics through practice and intuition.

Acoustic scientists at NYU have recently started to quantify that 
information by mapping the sound that radiates from a piano. Picture a 
seven-foot grand piano in a studio. The lid’s missing, so you can see 
all the strings. Researchers suspend a rod embedded with 32 microphones 
over the piano’s body.
