The speaker wants to move into a piece of music and share it with someone they love. The title points to a jazz track and a place, Granville Island, but the poem treats the song as a house, with winding paths, leaky corners, ghosts, and a huge claw-foot tub. Domestic details like instant coffee, a cat watching rain, and a slipper keep the fantasy cozy and ordinary rather than grand.
The speaker's feeling is tender, playful longing. They notice small things about the other person: the quiet way they move, a joke about the tub being built for giants. Music and intimacy blur together, so a broken note and a broken toe sit side by side, and a squeak becomes meaningful. The line breaks and missing punctuation make the poem drift and loop, much like improvised music. By the end, the speaker wants to live inside the beloved's eye, and the mood is dreamy, warm, and slightly wistful, like twilight.
