What to hear

How C major pulls and resolves

Use C as home, G or G7 as the strongest pull back to C, and A minor when you want the same notes to feel darker.

Guitar shortcut

First strum C, F and G as the I, IV and V chords. Keep returning to C until your ear recognises the tonal home.

Practice route

Turn the key into music

Play the C major scale once, strum every diatonic chord in order, then loop the I–V–vi–IV progression slowly. Finish short lead phrases on C while the Jamuzo groove plays.
