  After recent observational events like the LIGO-Virgo detections of
gravitational waves and the shadow image of M87* supermassive black hole by
Event Horizon Telescope (EHT), the theoretical study of black holes was
significantly improved. Quantities as quasinormal frequencies, shadows, and
light deflection become more important to analyze black hole models. In this
context, an interesting scenario to study is a black hole in the bumblebee
gravity. The bumblebee vector field imposes a spontaneous symmetry breaking
that allows the field to acquire a vacuum expectation value that generates
Lorentz-Violating (LV) into the black hole. In order to compute the quasinormal
modes (QNMs) via the WKB method, we obtain the Reege-Wheeler's equation with a
bell-shaped potential for this black hole. Both QNMs, the scalar and tensorial
modes, are computed for the black hole in the bumblebee scenario. Moreover, the
stability of the Schwarzschild-like solution and some bounds to LV parameters
are analyzed.
