The chapter constructs an energetic model of harmonic progression in which tense chords are signifiers of tonal functions (Riemann’s T, S, and D functions). The paradigm adopts the linguistic axes that Lacan mapped as metaphor and metonymy, which were crucial to the formation of a human subject at whose center lies désir. The theoretical claims build on the recent work of David Lewin (2007), Richard Cohn (2012a), Steven Rings (2011a), Dmitri Tymoczko (2011a), Brian Hyer (2011), and others but also reevaluate the earlier work of Ernest Kurth (1920), Hugo Riemann (1893), and Ernö Lendvai (1993). The chapter seeks to account for voice leading, modulation, and tonal diversity in a broad range of works
