Abstract: We present a see-saw A(4) model for Tri-Bimaximal mixing which is based on a very economical flavour symmetry and field content and still possesses all the good features of A(4) models. In particular the charged lepton mass hierarchies are determined by the A(4) x Z(4) flavour symmetry itself without invoking a Froggatt-Nielsen U(1)symmetry. Tri-Bimaximal mixing is exact in leading order while all the mixing angles receive corrections of the same order in next-to-leading approximation. As a cons
