I just bought a guitar and want to learn how to play without having to pay for lessons. I dont know any keys or notes or anything.
PluckandPlayGuitar has free video based lessons for absolute beginners and assume you know nothing or close to nothing.
It takes you step by step through the basic guitar chords one by one. There’s also lesson on guitar scales, techniques and some easy songs to play.
