A virtuoso concert piece, a transcription for violoncello of the Solo Sonata composed for viola in 2004. As in other works by János Vajda, in the well-proportioned structure of the solo sonata and in its wealth of melodic invention the presence of classical models is clearly perceptible, but conceived in a characteristically postmodern manner. The three movements represent three different characters: the dancing rhythm of the main theme reappears in the last movement as a lively toccata; the middle movement, which abounds in pre-classical figurations, evokes the singing, fantasia-like slow movements of the 18th century. The two outside movements are based on the same theme, and the characteristic intervals of this musical idea recur in the slow movement as well.

The work was premiered in 2006 by Balázs Kántor.
