Creep

Creep is the I–III–IV–iv chord loop. In F major that is F, A, Bb, and Bbm. Made famous by Radiohead. A haunting, tension-filled loop.

Roman numerals mark each chord's role in the key, not fixed chord names. Uppercase is major, lowercase is minor. Creep uses I–III–IV–iv. Change the key and the roles stay; the chord names move with it. In F major you play F, A, Bb, Bbm.

Loop F, A, Bb, and Bbm. Change on the first beat of each bar and keep the strum steady. If one change is hard, practice that pair slowly, then play the full loop again.

Songs built on Creep include Creep.

Creep (I–III–IV–iv) is one of the most reused patterns in Rock and beyond. Writers come back to it because the roles are strong: home, departure, pull, and contrast. It supports almost any melody and still feels complete when you loop it. Same functions, different songs.
