In his Sonata, Péter Wolf puts his style well-known from the character pieces of his previous piano series (Wolf-temperiertes Klavier, Jazz preludes) in the service of a demanding form. We can recognize the style that can be traced back to jazz and Bartók, the characters that tap like a toccata or swirl like perpetual motion, the singing lyrical melodies or even such playful turns as the baroque musette-like episode of the slow movement. Like Wolf's previous piano works, this multi-faceted composition, which sets high standards in terms of instrumental technique, was inspired by the outstanding pianist József Balog and gives the impression of his individuality as a performer.
