The lyrics for "echelon" are entirely instrumental, offering no direct narrative or emotional cues.
Without any lyrical content, it's impossible to derive a specific meaning or analyze the craft of songwriting. The absence of words leaves the interpretation entirely open to the listener's subjective experience of the music.
The piece relies solely on its sonic qualities to evoke feeling or tell a story. Any perceived meaning is therefore a projection onto the soundscape rather than an interpretation of textual elements.
Ultimately, the effectiveness of "echelon" as a piece of music is determined by its instrumental composition and the listener's personal connection to it.
