I'm Gonna Sit Right Down and Write Myself a Letter

I'm Gonna Sit Right Down and Write Myself a Letter by Fats Waller is played in the key of Bb. Originally recorded in the sounding key of Bb, 'I'm Gonna Sit Right Down and Write Myself a Letter' by Fats Waller is best approached with a Capo placed on Fret 5, enabling guitarists to execute friendly F shapes while fully preserving the studio pitch. To prevent hand fatigue on the challenging F barre chord, beginners can comfortably substitute an open Fmaj7 (xx3210) or small four-string F (xx3211) without sacrificing harmonic richness or vocal support. The primary progression challenge lies in switching between Bbmaj7/F and Eb: keep your fingers hovering close to the fretboard rather than flying off between changes. Set your metronome at an initial practice tempo of 79 BPM in 4/4 time to master the '↓ - ↓ ↑ - ↑ ↓ ↑' strumming groove, emphasizing steady downstrokes on beats one and three before accelerating toward the studio speed of 110 BPM.
