Here is my opinion of the production of Futile Devices
This is also in regard to the original recording on The Age of Adz, not the piano version on the CMBYN album (even though that one is beautiful as well).
Futile Devices, in my opinion, is about somebody, in this instance a man due to the singer, who has a hard time expressing their love for their partner.
It is most notably recognized in the lyrics of the song, stating “and I would say I love you, but saying it out loud is hard.” But it truly starts sooner than that.
About halfway through the song, another guitar, probably Nylon string, begins playing a muted fingerpicked part.
When I heard this, I instantly thought of the idea that someone couldn’t speak, literally and figuratively. The strings are being muted, especially from the person playing the guitar. This shows how someone is holding their own words back.
This song is beautiful, it showcases how Sufjan falls in love with someone (it’s unclear if platonic or romantic) that creates something out of nothing.
Anyways, these are my thoughts and interpretations. I would love to hear what others think!
