Abstract A model of high-{ital T}{sub {ital c}} superconductivity is proposed based on the following assumptions: (a) There are extended saddle-point singularities in the spectrum of electrons with a strongly enhanced density of states; (b) the interaction between electrons consists of a large and long-ranged phonon attraction and a small and short-ranged repulsion. It is shown that this model, having properties of both the {ital s}-wave and the {ital d}-wave approaches, can effectively explain most of the rather contradictory properties of these substances.
