It was before 1589 that Robinson became Princess Anne's (1574–1619) and Queen Sophie's (1557–1631) private music teacher at Elsinore, Denmark.
It was even suggested (Ward JM, see "Literature"), that it was never published at all, although Robinson seems to be referring to it in the first pages of his second book: "Right courteous Gentlemen, and gentle Readers, your fauourable acceptance of my first fruits from idlenesse, hath eccited mee further to congratulate your Musicall endeauours."
But there are also arrangements of other pieces of music, some of which are still rather popular: for instance "My Lord Willoughby's Welcome Home" (in: The Schoole of Musicke) or "Can she excuse my wrongs?"
It is supposed[1] to have included 40 canons on the then popular plainsong Miserere after arrangements by William Byrd and Alfonso Ferrabosco.
Furthermore, The Schoole of Musicke contains eight short pieces, seven of them called "A Psalme" in the chapter "Rules to instruct you to sing".
