Heinrich Ignaz Franz Biber was considered one of the greatest violin virtuosos of the Baroque period. He developed significant improvements of the violin technique of his time. He not only surpassed the musical standards of his time with respect to virtuoso demands on the musician, but he also created works whose musical substance and fantasy were far beyond the standards of his time. The Balletti und Sonaten für Clarintrompeten und Streicher are characterized both by extreme densitiy and complexity on the one hand and blooming openness, grandour of sound and dance-like character on the other.
