Hi Margaret.
Reading TAB for fingerpicking is quite easy. Keep the thumb of your right had for the lowest (fattest) 3 strings (E,A andD) and then your index finger for the G string, middle finger for B string (thinnest but one) and ring finger for the E (thinnest string).
The TAB diagram shows the six strings fattest on bottom and thinnest on top, with the numbers on each string representing which fret the fingers of your left hand should hold down.
Usually the thumb will play on the beat and the fingers will pick out the melody or provide an accomanyment.
Persevere.It really doesn’t take long to master.
Remember Practice SLOW Learn FAST.
