Read the following excerpt concerning the history of musical tuning:
"Traditional musicological narratives often frame the eighteenth-century triumph of equal temperament—a tuning system that slightly compromises the acoustic purity of all intervals so that none are intolerably dissonant—as the inevitable culmination of theoretical acoustics. This view, however, neglects the socio-economic imperatives of the period. The rapid proliferation of the *clavier* in middle-class households fundamentally altered the landscape of musical consumption. Unlike professional court musicians who possessed both the time and the technical acumen to re-tune their harpsichords when transitioning between disparate keys, bourgeois amateurs demanded a uniform system that allowed a single static tuning to accommodate an ever-expanding repertoire of published sheet music. Thus, equal temperament was less a mathematical victory than a pragmatic concession to a new demographic of consumers."
Regarding the passage's logical structure, what is the primary rhetorical function of the reference to the growing prevalence of the *clavier*?
- It introduces a socioeconomic catalyst that justifies the author's departure from the traditional explanation of a historical shift.Answer
- BIt illustrates a theoretical advancement in acoustics that resolved the intolerable dissonance of prior tuning methods.
- CIt specifies the instrument that ultimately allowed eighteenth-century theorists to achieve perfect acoustic purity.
- DIt contrasts the technical acumen of court professionals with the mechanical limitations of the instruments available in middle-class households.
- EIt outlines a cultural consequence that resulted directly from the mathematical victory of equal temperament.
