Someone asked a question about why picked guitar strings sound different from finger-plucked strings. A complete answer to this is very math-heavy for this site.
I posted my answer here: https://music.stackexchange.com/a/84894/474
Unfortunately, this does not appear to be one of the SE sites that has MathJAX enabled, so my equations are just the raw TeX code. Can MathJAX be enabled to allow proper rendering of the answer?
