Giovanni Girolamo Kapsperger (c1580-1651) – or Johann Hieronymus Kapsberger the name which he was given at his birth was an Austrian-Italian virtuoso performer and composer of the early Baroque period. A prolific and highly original composer, Kapsberger is chiefly remembered today for his lute and theorbo (chitarrone) music, which was seminal in the development of these as solo instruments.
