The piece aspires to music and employs a musical toolset – in the mode of jazz, or a fugue – in that a limited set of themes are returned to over and over, building on themselves through repetitions that are successively altered in creative or unexpected ways (even mischievously including a section that is actually a stanza!), yet all driving toward the same end and reaching a definitive conclusion. This allows the reader (or listener) to access a degree of mystical or trance-like consciousness during his or her experience of the text.
