This article presents JIG, a system for improvisation on jazz ballads. It was described previously in a Master's Thesis [4]. JIG generates so called 'formulaic' improvisations. It uses constraints, in combination with probability-driven randomness to generate note-attributes. In this way, numerous different improvisations can be generated on a single song. JIG has been incorporated in SaxEx, a case based reasoning system for generating expressive performances of jazz ballads.
