What a Wonderful World — reimagined in F A C G C E

Originally by Louis Armstrong (Standard tuning, key of F major) Tuning used here F A C G C E — an open F9 voicing Key idea the open strings already spell the song's own maj7/9 color

This isn't how the song was originally played. The standard is normally worked out in Standard tuning — most alternate tunings actually fight this kind of tune, since they're built for modal, drone-based folk harmony, not the ii–V–I jazz motion this song runs on. F A C G C E is the exception: strum it open and you already hear F, A, C, G, E — the root, third, fifth, ninth, and major seventh of Fmaj9, the song's own home chord, ringing for free before a single finger touches the fretboard.

The tune sits in F major and leans on real jazz motion: a ii–iii–IV push through Am7 and Bbmaj7, back down through Gm7 into a dominant C7, and home to F. Voiced in F A C G C E, that same motion falls into open, low-fret shapes — the tuning's own resonance doing half the work a standard-tuning jazz chord-melody arrangement normally has to fight for.
