Charles Frederick Frantz provides a quantitative and qualitative analysis of Debussy’s music through the lens of Bergson’s philosophical perspective of durée, revealing his "revolution" in musical time.

In fin-de-siècle Paris, Debussy was revolutionizing musical time while Bergson was establishing a metaphysics that challenged the notion of measured or spatialized time. Bergson argued that real time or durée could be grasped only through intuition as opposed to analysis. Debussy eschewed analysis of music, declaring that separating it into parts was better left to engineers. Debussy’s music and Bergson’s durée were conceived and imagined in the environs of nature. The cycle of seasons, the gracefulness of a blooming flower, or a gentle breeze all suggest continuity, flow, and uninterrupted rhythm. The time of nature is the time of Debussy’s music and Bergson’s durée. Debussy’s use of open forms and Golden Sections create a time world of an expanded present, never ceasing. Bergson’s perception of real time is ever-changing, bringing the past into the present and open to unforeseen novelty.
