The lowest note on a violin is a G.  With the standard tuning (440 Hz = A),
that G is approximately 196 Hz.  In principle, there is no upper limit on
any stringed instrument, but the high A at 3520 Hz, three octaves above the
A string at 440 Hz, is about as high as violin music ever gets.  "Hz" (from
Heinrich Hertz, 19th-century scientist) just means cycles per second.  A
string at 440 Hz is thus vibrating back and forth 440 times every second.
