Two violin strings are tuned to the same frequency, 277 Hz. The tension in one string is then decreased by 1.92 percent. What will be the beat frequency heard when the two strings are played together?

pretty much, all else being constant and for the purpose of the problem

\[\frac{ f _{1} }{f _{2}} = \frac{ \sqrt{.9808T} }{ \sqrt{T}}\]
