The modular symmetry is considered as one main origin of non-abelian discrete flavour symmetries. The latter have been widely used to explain lepton flavour mixing. Recently, the modular symmetry was suggested as the direct origin of lepton mixing. In the new framework, lepton mass textures originate from modular forms and mixing angles are fixed after the modular field gains a VEV. In my talk, I will introduce this novel approach and generalise it by including multiple moduli fields.
