It is not only because of Gershwin's enthusiasm for the organ that his '3 Préludes' virtually suggest themselves to be performed on the organ. They are preludes in a traditional style, character pieces with idiomatic jazz figurations and exciting harmonies. Therefore it is certainly appropriate to use these miniatures in churches and especially in organ concerts. Jazz music on the church organ? Why not! Although notated jazz music is not real improvised jazz music, Gershwin undoubtedly influenced jazz (Miles Davis, Herbie Hancock), and his preludes are a valuable addition even to the organ repertoire.
