PreliminariesAlthough published as recently as 2006, James Hepokoski's and Warren Darcy's much heralded and substantially delayed Elements of Sonata Theory has been a significant presence in the field of music theory and analysis for over a decade.1 Indeed, one reads this monumental work with an unavoidable sense of déjà-lu . Draft copies were frequently quoted in conference papers and articles for several years prior to publication. Also, many of the book's key precepts are aired by both authors in a variety of publications dating from 1992 onwards dealing with works by Beethoven, Bruckner, Sibelius and Richard Strauss amongst others, as well as historical issues such as the reception of Beethoven's symphonies and theoretical concepts including the so-called 'sonata principle', 'rotation', 'deformation' and the 'medial caesura'.2 Given the intense level of advance exposure for the authors' ideas and the wealth of insightful precursor texts about sonata form in the High Classical Era, it is not self-evident that there is actually a gap in the existing literature for Elements of Sonata Theory to fill, all the more so since the book was pre-empted by its main market competitor, William Caplin's commanding and elegantly concise Classical Form .3 Nevertheless, closer inspection reveals that the publication of Elements of Sonata Theory is justified at least by its encyclopaedic aspect, by the incorporation of just enough new material (the concluding three chapters on Mozart's concertos in particular) and by the elaboration and refinement of some fundamental premises.Chapters 1 to 4 situate Sonata Theory within the field and introduce its core precepts. Hepokoski and Darcy broadly identify three main strands in existing thought about sonata form: the 'sonata principle' elaborated first by Edward Cone and then by Charles Rosen, which stresses the notion that sonata movements dramatise fundamental properties of the Classical Style, especially polarisation and resolution, and which thus requires that non-tonic material in the secondary and closing areas of the exposition be recapitulated in the tonic or else 'brought into a closer relation' with it (p. Bonds labels the 'generative view', first expounded in detail by Schoenberg, which regards sonata forms as products of material process. 4 In contrast, Sonata Theory claims to transcend all these viewpoints, positing that classical composers are in 'dialogue' with a constellation of 'generic defaults', which are hierarchically organised according to frequency of usage. When classical composers override 'standard options', they 'deform' generic conventions. Naturally, the 'genre sonata form' is subject to 'diachronic transformation', with the result that constellations of norms undergo incremental change: a deformation in, for example, Beethoven can 'become a lower-level default in Schumann, Liszt or Wagner' (...
