How to memorize the fretboard
The following is how you memorize the fret board quickly and efficiently. When learning, memorizing or practicing guitar scales or guitar modes, it is extremely helpful to memorize the notes on the fret board. If you memorize the notes on the fretboard, you will be able to connect scales and locate the root of keys that you are playing in while soloing, easily. You don’t necessarily have to memorize all the sharps and flats, just remember where all the: A, B , C, D, E, F and G notes are. I first started off memorizing where the notes are on the low e and the a string. From there you can develop patterns in your head and see where all the flats and sharps are. The flats are 1 fret lower than a note. For example Ab (A Flat) is 1 fret lower than A. A flat is on the 5th fret and Ab is on the 4th fret. The Sharps are one fret higher than a given note. For example, A# is higher than Ab. I definitely recommend memorizing or becoming familiar with the fretboard.
