In what follows I will develop an account of Fairbairn's object relations theory as I have understood and developed it, and, apply that theory to an understanding of the threeact opera King Roger, Op. 26 (1926) by Karol Szymanowski. My Fairbairnian approaches to the opera come from my previous work on Fairbairn's object relations theory. In order to fully understand the first of the approaches I employ you may need to read my book Personal Relations Theory (Clarke, 2006), in particular chapters one, five, and six. In order to fully understand the second of the approaches I am using you need to read Thinking Through Fairbairn (Clarke, 2018a), in particular chapters two, three, and four, as well as my paper in the journal Attachment (Clarke, 2018b) on MPD/DID and Fernando Pessoa's heteronyms.
