Resumen: We present a simple formulation of the inclusive and exclusive semi-hadronic decays of the tau lepton using QCD-duality finite energy sum rules (FESRs). We find that the tau decay is a good laboratory for measuring the QCD scale Λ. Within the present experimental accuracy, we obtain A_MS= (100-200)MeV to four loops. This prediction can be sensibly improved once the experimental situation has been clarified.
