GuitarChords.net is a no-cost site that teaches you how to play guitar chords. The charts are easy to read. The words under each chart are simple. You can pick up a guitar and begin playing on the same day.
Each chord starts with a picture. Then a short list tells you where each finger goes. The list names the string, the fret, and the finger. It also tells you which strings to skip and which strings to play open. The fret numbers are the actual numbers on the neck, so you do not have to guess. The chart looks right on a computer and on a phone.
Start with eight easy chords: C, G, D, E minor, A minor, E, A, and F. These shapes show up in a lot of songs. After that, you can open any other chord and read it the same way. A brief page explains the marks. An x means do not play that string. A 0 means play it open, with no finger down. The numbers 1, 2, 3, and 4 are your fingers, from index to pinky.
You do not need to sign up to see a chart. Major chords sound more upbeat. Minor chords sound sadder. The rest is just the shape. GuitarChords.net is for those new to guitar. That can be a young person learning a first song, or a adult who is new to the guitar.
