What is FretMapper for?
FretMapper exists for the player who has just bought their first acoustic guitar and is staring at a chord chart wondering whether the dots represent strings or frets. Every page on this site is built around two questions: What do my fingers actually need to do? and Why does it sound that way?
The catalog is intentionally limited to public-domain and traditional songs — the music that has been the first material for acoustic learners for a hundred years. You won't find chart-topping radio hits here, because copyright restrictions on tablature would force us to compromise on accuracy or completeness, and we'd rather have 520 songs you can study end-to-end than a thousand stubs. Each song page includes a full chord progression, a strumming pattern, a step-by-step practice plan, and links to the tutorials that cover the underlying technique.
Reading guitar music for the first time is a small literacy project. Start with the chord-diagram walkthrough, learn three open chords from the chord library, and then play your first song from the beginner index. That's a complete first week. We'll be here when you're ready for week two.
