Question

Read the following passage regarding the history of musical tuning systems. Match each specific textual phrase or argumentative move from the passage (on the left) to its abstract rhetorical function within the author's argument (on the right).

PASSAGE:
The history of Western classical music often frames the widespread adoption of equal temperament tuning in the eighteenth century as a triumph of rational progress. According to this prevailing narrative, replacing the myriad meantone and well-tempered tuning systems with a mathematically uniform division of the octave liberated composers from the restrictive acoustic dissonances of older systems. Equal temperament, this view asserts, was 'the inevitable culmination of a centuries-long quest for acoustic symmetry.'

However, a closer examination of the material realities of seventeenth- and eighteenth-century musical culture reveals a more pragmatic, and less idealistic, driver for this shift. As 'the financial ledgers of court instrument builders' demonstrate, maintaining multiple keyboard instruments—each tuned to accommodate specific key signatures for different pieces—was prohibitively expensive. The push toward equal temperament was thus less about achieving theoretical perfection than about economic efficiency; a single uniformly tuned harpsichord could serve an entire court's varied repertoire, albeit imperfectly.

Furthermore, while equal temperament indisputably 'facilitated the complex harmonic modulations' that would characterize later Romantic music, this versatility came at a significant aesthetic cost. By smoothing out the distinct acoustic colors of different keys—where previously D minor might possess a genuinely different resonance than E major—equal temperament inaugurated a homogenization of affective musical character. The rationalization of the octave, therefore, should not be viewed merely as an artistic liberation, but simultaneously as a 'subtle flattening of the musical palette.'
