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 Bb
Bb major uses Bb, Eb, and F, which are all barre or partial chords. Songs recorded in Bb are usually played with a capo on the 3rd fret using G-major shapes.
