That there was a possible collaboration between Thomas Morley and Shakespeare has long been a source of speculation and controversy among scholars. The discussion has generally centered on the validity of certain musical evidence, namely, the songs, ‘ It Was a Lover and His Lass’ from As You Like It and ‘O Mistresse mine’ from Twelfth Night, to which Morley may or may not have composed the music for the first performance of the play. It is not the purpose of this article to enter into the controversy, but rather to re-examine the problem of the relation between text and music in the case of the latter song, the chief bone of contention, and perhaps to throw some more light on the question.
