My contrabass clarinet's lower notes make the computer
screen shake and pulsate. Why?

Resonance.  Your computer screen apparently resonates at a frequency
near the contra's lower range.  If you play loud enough, the screen
shakes.  There are probably a number of things in the area that shake
too, its just that it is easier to notice when the computer screen
shakes due to the image blurring.  Other resonances are generally not
noticed unless something rattles or buzzes.

When I was in high school, my bari sax practicing used to cause our
TV screen to blur, much to my sisters' annoyance.  Is it any wonder I
practiced so much?... ;-)
