A guitar chord consists of three or more notes played at the same time. This is done by strumming the guitar strings. Learning guitar chords is one of the first steps in learning how to play guitar. There are many different types of guitar chords.
My fabulous guitar skills are self-taught. I don't even know the names of the real chords. I name most of the chords I play, the "Ice-Berg" (G-sharp) and "Bear Claw" (A) based off of my finger formations when I play them.
