Chord Tips
Finger Placement
Press strings just behind the fret (not on top) for a clean sound. Keep your fingers curved and use fingertips.
Reading Diagrams
✕ means don't play that string, 0 means play it open, and numbers show which fret to press. Cycle shapes when a chord has multiple voicings.
Ukulele & Piano
Switch to Ukulele for GCEA diagrams or Piano for the reference chart. Blue keys show which notes to press for each chord.
