Two disciplines, psychoanalysis and music, are synthesized here with an eye to the origins and vicissitudes of shame and guilt as seen in the emotional disintegration of the eponymous heroine of Donizetti's opera Lucia di Lammermoor. Lucia's affects and her intrapsychic and interpersonal dynamics are heard in the music itself. A psychoanalytic and musical analysis of the opera, taking Lucia's dynamics as a quasi-substitute for clinical material, illuminates the intersections between certain theoretical aspects of the two disciplines. Both manifest and latent themes are expressed through the music of Donizetti's score.
