The excerpt compares a pianist to a slow swimmer, suggesting a serene yet isolating experience. Both the pianist and a lover engage deeply in their respective realms, immersing themselves in a world where external distractions are absent. The piano's lid symbolizes a barrier that limits external influences, creating a unique space for connection and artistry.
However, this perfection found in their deep focus is also depicted as detrimental. The idea that an ideal state can be harmful points to the inherent challenges in striving for perfection in love or art. Ultimately, the passage reflects on the complexity of passion and the isolating nature of fully immersing oneself in an experience.
