Learn
Four written guides to the things a song page on this site states but does not explain.
Everything under a song's address here is produced by a machine listening to a recording: the chords, their timing, the key they agree on, whether a capo would help. That is useful only to a reader who already knows what those words mean, and most people arriving at a chord site do not — which is a failure of the site rather than of the reader.
So these pages fill the gap in the other direction. Each one takes something the catalogue already computes and explains what it is, what to do with it at the instrument, and when not to trust it. Each ends with songs from this catalogue that actually demonstrate the lesson, so you can hear the thing you have just read about rather than taking it on faith.
How to read a chord diagram
The six lines, the dots, the numbers down the side — and the same chord drawn on a keyboard.
What a key is, and what it tells you
Why four chords keep turning up together, and what to do with the key once you know it.
Barre chords, and when a capo replaces them
The hardest thing a beginner meets, and the seven-euro clamp that makes half of it unnecessary.
The open chords worth learning first
Eight shapes that between them cover an enormous number of songs, in the order to learn them.
They are written to be read in any order, but if you have never held a guitar, start with the open chords.
