There is no concrete evidence that he before 1604 visited Italy and adopted the name Giovanni Coperario, which he kept after returning home; the story nonetheless persists. Almost all of his works are secular, but he was in distinguished company in appearing in Leighton's 1613 The Teares or Lamentacions of a Sorrowfull Soule. He published two books of lute songs (Funeral Teares and Songs of Mourning) and was a prolific composer of fantasias, some ninety in from three to six parts being extant. suites for consort, some Italian villanellas, and a treatise Rules how to compose, written before 1617, a practical manual with original musical examples. His fantasias for viols show the progress of idiomatic instrumental writing, but more important are his four consort suites, both for their novel medium of one or two violins with bass viol and organ (although the music for the organ is merely a reduction of that allotted to the other three instruments), and for their development of the concept of the suite: each consists of a Fancy, an Almane, and a Galliard.
