Master Blaster by Stevie Wonder is played in the key of F at a intermediate difficulty level, originally released in the 1980s. It uses 2 chords — F Bb — arranged in the I-IV progression.
About the I-IV progression
The I-IV two-chord vamp alternates between tonic and subdominant. It's a favorite of reggae, folk, and any genre where the harmony steps back to let the groove drive.
Playing in the key of F
F major is a stretch for beginners. The F chord itself needs a barre or partial shape, and Bb (the IV chord) is a full barre. Many players capo the 3rd fret and use D-major shapes to make this key easier.
