Song Meaning

The lyrics for "扉 (Key)" are entirely instrumental, offering no direct narrative or emotional text for analysis. Without any lyrical content, it's impossible to determine a specific meaning, theme, or emotional tone. The absence of words leaves the interpretation entirely open to the listener's experience of the music itself. The piece invites personal reflection, allowing the soundscape to evoke individual feelings and associations. Therefore, any meaning derived would be subjective and purely based on the auditory experience rather than textual interpretation.
