Quasinormal modes are characteristic oscillatory modes that appear when a black hole is perturbed. In this work we focus our attention on computing them with the WKB approximation method. First, we start by revising some of the pioneering methods to calculate them using this approach. We then present a recently developed technique that allows us to achieve very high-order calculations of WKB series in perturbation theory and automates the computation of such modes
