Hi, I am Franklin Taggart. I am a guitar player and a guitar teacher. I would like to show you a C7 chord. Your first finger plays the first fret of the second string. Your middle finger plays the second fret of the fourth string. Your ring finger plays the third fret of the fifth string and your pinky plays the third fret of the third string. For the C7 chord you strum the bottom five strings. Thats how you make a C7 chord.
