How did you learn all the chords (guitar) up and down the fretboard quickly?
First you have to learn the open chords. That takes time, and I don’t know any other method than practice. When you don’t actually have the guitar in your hand, visualize it in your mind. It helps. As far as learning all the chords up and down the fretboard, I assume you’re talking about barre chords(?) You can barre any chord, but most commonly people barre E and A formations with their minor and 7th variations. Then all you have to do is memorize the notes on your low E and A strings. If you count up the fretboard on your low E string, the notes go: 0=E 1=F 2=F# / Gb * 3=G 4=G# / Ab * 5=A 6=A# / Bb * 7=B 8=C * 9=C# / Db 10=D 11=D# / Eb **12=E The asterisks show the fret markers. If you barre across the first fret and finger an E, you are playing an F. Do the same thing on the 2nd fret and you’re playing an F#. By counting up the fretboard following the notes on the E string, YOU CAN PLAY ANY MAJOR, MINOR OR 7th CHORD!! Use the fret markers to help you count. Of course, this same form
