Play it easier with a capo

  • Capo on fret 1 + C7 shape → sounds as C♯7
  • Capo on fret 2 + B7 shape → sounds as C♯7
  • Capo on fret 4 + A7 shape → sounds as C♯7
  • Capo on fret 6 + G7 shape → sounds as C♯7

If barre chords are hard, clamp a capo and play an open shape — it sounds exactly the same. The Buskermate app can move a whole chord sheet to any capo position for you.
