This is all very simple. The whole song follows this same pattern: Am C F G It's on the 3rd fret, and these chords are relative to the capo. It's 3/4 timing, like a waltz, so strum appropriately. Each chord gets exactly 4 and this does not change. Flightless Bird, American Mouth by Iron & Wine [Verse 1] C I was a quick wet boy Am Diving too deep for coins F All of your straight blind eyes G Wide on my plastic toys C And when the cops closed the fair Am I cut my long baby hair F Stole me a dog-eared map G And called for you everywhere [Chorus] C Have I found you? Am F G Flightless bird, jealous, weeping C Or lost you? Am American mouth F G Big bill looming [Verse 2] C Now I’m a fat house cat Am Cursing my sore blunt tongue F Watching the warm poison rats G Curl through the wide/white fence cracks C Kissing on magazine photos Am F Those fishing lures thrown in the cold and clean G Blood of Christ mountain stream [Chorus] C Have I found you? Am F G Flightless bird, brown hair bleeding C Or lost you? Am American mouth F G Big bill, still going down --Evan A.
