In 1993, Ligeti completed his Violin Concerto after four years of work. Like the Piano Concerto, the Violin Concerto uses the wide range of techniques he had developed up until that point as well as the new ideas he was working out at the moment. Among other techniques, it uses a passacaglia, "microtonality, rapidly changing textures, comic juxtapositions... Hungarian folk melodies, Bulgarian dance rhythms, references to Medieval and Renaissance music and solo violin writing that ranges from the slow-paced and sweet-toned to the angular and fiery."
