Interpolation is a fundamental logical property with applications in mathematics, computer science, and artificial intelligence. In this paper, we develop a general method of translating a semantic description of modal logics via Kripke models into a constructive proof of the Lyndon interpolation property (LIP) via labelled sequents. Using this method we demonstrate that all frame conditions representable as Horn formulas imply the LIP and that all 15 logics of the modal cube, as well as the infinite family of transitive Geach logics, enjoy the LIP.
