St. Louis Blues

The speaker is grieving because her lover has left town. The setting sun seems to deepen her loneliness, and she imagines leaving too if tomorrow feels as painful as today. Her mood moves between sadness, anger, and fierce devotion: she resents the man’s departure but still says she will love him for life.

Several expressions make the feelings vivid. “Blue” means deeply sad, not literally the color. Saying the man has “a heart like a rock” suggests he is cold or uncaring. The image of a woman pulling him by her “apron strings” implies that she has strong influence over him; the speaker blames this other woman’s appearance for his leaving, though that may also reflect jealousy rather than fact. “Pack my trunk” is a practical image of preparing to go away and start elsewhere.

The lyrics leave some things uncertain. The speaker sounds convinced that another woman caused the breakup, but we cannot know whether her explanation is accurate. Her final declaration of lasting love may express sincere loyalty, or it may contrast with her hurt and frustration. The song captures how love can persist even when someone feels abandoned and powerless.
