So it was in Petrarch's, who was a lutenist, and who "tried" his verses, to see how they would go to the instrument.

The two blessed spirits, meanwhile, whom the bird mentioned, like the fingers of sweet lutenist to sweet singer, when they quiver to his warble as it goes, manifested the delight they experienced by movements of accord simultaneous as the twinkling of two eyes.[30] Dante turned to receive his own final delight from the eyes of Beatrice, and he found it, though the customary smile on her face was no longer there.

Shakespeare's "intrinsic friend," John Dowland of Dublin, was one of the greatest lutenists in Europe from 1590 to 1626.
