Jazz has long been  an element in Jerry’s concert works and INTERPLAY is a jazz infused piece using angular melodic material inspired by the style of the  Be-Bop era in jazz. Prelude  introduces a descending  chromatic 3rd which is a basic motive of the  melodic  material explored and developed in the  Invention. Melodically, the lines give a  sense of improvisation  and you may detect some Impressionist influence in the superimposed harmonies being grounded in free tonality. Performing is the composer.
