Keyboard music was rarely printed for most of the 16th century, but in an attempt to provide for amateurs, printers began publishing arrangements of popular vocal works for keyboard which formed the earliest known repertoire for the instrument. The focus of this release is four composers who worked in this medium: the Cavazzonis and Gabrielis, who documented the workings of ricercares, chansons, hymns, and toccatas of their time. These works evince the long development of the Italian Renaissance keyboard style.
