Disarm by Smashing Pumpkins is played in the key of F at a intermediate difficulty level, originally released in the 1990s. It uses 4 chords — F C Dm Bb — arranged in the I-V-vi-IV progression.
About the I-V-vi-IV progression
The I-V-vi-IV pattern is the most common chord progression in modern pop. It moves from the tonic home chord to the dominant (V), drops to the relative minor (vi) for emotional weight, then resolves through the subdominant (IV) back to home. Hundreds of hit songs are built on this shape, from "Let It Be" and "Don't Stop Believin'" to nearly every four-chord Top 40 song of the past thirty years.
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.
