What you need
The 90-Minute Plan
The barre chord uses one finger (usually index) to press multiple strings at once. Start with 2-string barres on frets 3-5. Place your index finger flat, press down hard, and pluck each string separately to ensure it rings clearly.
Practice pressing at frets 1, 2, and 3 with your index finger across 2-3 strings only. Hold for 30 seconds, release, rest. Do 8 repetitions. Your goal is building finger independence and endurance.
Place index on fret 1 across all 6 strings. Add middle on fret 2 (A string), ring on fret 3 (D string), pinky on fret 3 (B string). Test each string rings clearly. If not, adjust finger angle.
Start with open C major. Change to F major barre (1st fret). Back to C. Repeat 10 times slowly. Rest between attempts. The transition is where difficulty lives.
Learn the progression C-F-G or F-Bb-C. Play each chord cleanly for 4 beats. Record yourself. Even slight fatigue is normal—stop before pain and practice daily for faster strength gains.
Angle your index finger so the barre sits on the fret (not between frets), and practice 5 minutes daily rather than 30 minutes once a week.
