Music my rampart, and my only one.

In this line, “music” functions as a metaphor for an inner fortification—an emotional and imaginative defense against pain, loneliness, or the pressures of the external world. Calling it a “rampart” suggests not mere comfort but protection: something that holds the self together and keeps despair or intrusion at bay. The phrase “and my only one” intensifies the claim, implying that other supports (people, institutions, faith, or social belonging) have failed or are unavailable, leaving art as the sole refuge. The line thus captures a modern lyric stance: the artist’s reliance on aesthetic experience as both sanctuary and survival mechanism.
