The Fsus4 chord

The Fsus4 chord is held breath, looking for resolution. Its notes (F - Bb - C) form a suspended fourth, which is why it shows up across classic rock, gospel and praise music. Songwriters pick the Fsus4 when they want tension that begs to resolve, and on guitar it sits in barre-chord territory for most useful keys. The voicings, theory, progressions and song references that follow are organised so you can skim once or settle in for the full picture.

The Fsus4 chord (F - Bb - C) is a suspended fourth. Its intervals are root, perfect fourth, perfect fifth. Functionally it lives at home in a closely related major key as the passing chord, but you'll also find it in a closely related major key as the passing chord.
