Musical Self-Borrowing in Ottocento Opera and the Composer's Toolbox

Self-borrowing was a common practice in primo ottocento opera. Even though commentators of the era could find it somewhat troublesome, composers indulged in the practice. Drawing on existing scholarship, and reflecting on the work of my co-contributors to this journal issue, I ponder a few sundry notions about the procedure and its context, addressing theoretical, historical and practical perspectives relating to composers, historical commentators, listeners and modern-day scholars. I begin with a survey of terminology that has been applied in discussions of self-borrowing and a review of the manner in which selected present-day scholars have characterized the practice. I then consider the nature of self-borrowing in the ottocento opera repertory against a backdrop of contemporaneous theoretical discussions about how to compose opera, and I contemplate the extent to which self-borrowings in this repertory can be deemed to bear meaning. I conclude by raising the possibility of applying concepts from cognitive theory to operatic encounters with self-borrowing, proposing that the practice served as a tool for composers to fuel expectation, predictability, anticipation and even surprise to enhance musical pleasure. My purpose is to prompt reflection on the reasons behind as well as an appreciation for the value of this oft-maligned compositional 'tool' in the interest of gaining insight into its impact on the listening experience and the evaluation of musical works.
