How to Play It

  • Start your strum from the A string and avoid any strings marked X.
  • Keep your fingertips close to the fret wire so the C7 chord rings without buzz.
  • Emphasize the b7 with a slight accent when comping a blues.
  • Practice quick I7 → IV7 → V7 changes.

Suggested Strumming Pattern

Down, down-up, down-up, down-up; start slowly and listen for every open string to ring clearly.

Common Mistakes

  • Playing a maj7 shape by mistake — the b7 is one fret lower.
  • Strumming into muted strings instead of stopping at the first ringing string.
