The reputation of Polish pianist, composer, conductor and educator Józef Wieniawski has proved less robust than that of his famous elder brother, the violinist Henryk Wieniawski, but during his lifetime he was considered one of Europe’s finest musicians. The brothers performed together extensively for a time, and the virtuoso elements in the violin part of the youthful Allegro de sonate and Grand Duo polonais can be credited to Henryk. Józef’s Violin Sonata reveals elegant sophistication, expressive depth and jocular playfulness in exploring the full expressive range of both instruments.
