What ties this exquisitely played collection of lute pieces together is that all appeared in the anthology whose pieces were chosen by one John Cozens. Searching through 16th-century manuscripts in the 1960s, Rooley evidently discovered many such personal collections, designed for each owner’s amusement and edification. Found in the Cambridge University library, the John Cozens Lute Book was distinguished in Rooley’s eyes by the collector’s taste, the “florid” ornamentation, and clarity. Rooley recorded a quarter of the music in the manuscript.
