At first I did not really understand this poem, but then I read the analysis that I found by Charles Oliver, and that really helped me to understand it better. Oliver brings up the issue of whether or not the lover that Whitman mentions is a male or female. That he brings this up at all shows previous knowledge of Whitman's other forays into the world of homosexuality. Oliver just assumes that the lover is a woman based on the title of that particular section being "Children of Adam". Anyway, that whole question is also typical of Whitman. He often left things deliberately ambiguous, which, at the time, was pretty scandalous. Now it just kind of seems like a waste of time.
The Everyman is present in this poem if you squint and read heavily in between the lines. Anyone could be walking past a church or through a forest and hearing music and the wind respectively. Hearing such things, many would become reflective, and some might even think of their lovers. That's kind of a far leap, but it could happen.
Whitman uses a lot of imagery in this poem. He likens his lover's pulse to little bells ringing in his ears. He describes the sound of the pipe organs as "solemn-sweet", which I liked because those two words really do describe how a pipe organ sounds.
Self is really only present in this poem, as far as I understand, in the way the poet is reflecting on something that he holds dear as he hears the wind and the pipe organ. Our Self is shaped by those around us, and the poet has obviously been deeply impacted by the person he is thinking of in the poem.
Whitman successfully manages to relate music to love, and then he reflects upon that love. Though this poem was short, it still managed to artfully capture a moment in time.
