A complete description is given for the unstable spectrum of the Euler equation linearized about shear flows with sinusoidal profiles. The spectral problem is treated analytically and numerically. The spectral asymptotics are determined using the method of averaging for general rapidly oscillating profiles. Such flows are always unstable.
