This is a series of introductory lectures on QCD and chiral theories for master and PhD students. It will be in English. 
The topics are: Groups, QCD Lagrangian and its symmetries (with special attention to dilatation symmetry and chiral symmetry), 
large Nc, multiplets of quarks, glueballs, effective approaches of QCD, such as chiral models and chiral perturbation theory.
