How do i learn the guitar fingerboard quickly?
For classical guitar, you will stay in “first position” for a quite a while. That’s down at the first frets. Buy a book of “graded” (harder and harder) first-year guitar music and you’ll soon learn those notes, and you’ll soon find yourself moving up the fretboard, piece by piece. If you mean guitar for popular music, for learning chords, there are scads and scads of guitar chord charts available over the Internet. I’ve sited two below. Pair these charts with your favourite popular music — and you’re in business. Finally, try starting with pieces that are in keys that are simple for a guitar, such as the key of C major (no sharps or flats) or G major (one sharp).
