In the first movement, emphasis is placed on a slow and expansive phrase flow, with the intention of maintaining a deep resonance through extensive use of the pedal. Fluctuations in tempo and dynamics are characteristic. In contrast, the second movement maintains a fixed tempo and minimizes pedal usage, effectively employing irregular meters, rests, staccatos, and accents to develop a dry sound world.
