E 6 string-
A 5 string
D 4th string
G 3rd string
B second string
e first string
That's in standard tuning
Learn the low E 6th string to the 12th fret. The twelve fret starts all over
Then you will know the high e 1st string..
Go to the scale find tool.. it list them out.. you may have to change the note number to letters with the selection at the bottom of the scales page..
When you fret a note say it's name..
Also there is an L trick.. find A at the sixth the string.. fifth fret... on the 5th fret go 2 strings to the fourth string and then two frets higher you find another A..
Link to C major scale.. # (sharps) and b (flats)
