What do I do to get better curves?

Run the following code in mathematica:

a[k_,w_,p_,q_]:=(k^2-w^2)^2 Sin[p]Cos[q]+4k^2 p q Cos[p]Sin[q]

The curves thus obtained are very inaccurate. I tried raising the 
PlotPoints and WorkingPrecision opions of ContourPlot, but it doesn't 
work. Morevoer, you see that the only parameter that shows up, 'r', is 
an exact rational number. I don't know what else to try. Thanks.
