We analyse the possibility of describing quark masses, mixing and CP violation in $$ {S}_4^{\prime } $$

symmetry (the cusp) plays a role in generating quark mass hierarchies and discuss the role modular form normalisations play in such constructions. We find that fitting quark data requires explicit CP breaking, unless a second modulus is introduced.
