Difficulty: Moderately Easy
Step1
Set your key. For this example, we'll use the key of A, so start with the A note. This is located at the fifth fret of your bottom bass guitar string.
Step2
Play the A, then move down two frets to G and down two more frets to F. Listen to the descending first notes of the song.
Step3
Go back up from the F. Play a G and then three A notes.
Step4
Pluck three G notes in succession. You can easily recognize this part of the song.
Step5
Play one A and two C notes (eighth fret). You just finished the first part of the song ("Mary had a little lamb, little lamb, little lamb").
Step6
Start over and play the beginning notes again ("Mary had a little lamb").
Step7
Pick out another A and two G notes ("whose fleece was").
Step8
Follow with another sequence A, G and F ("white as snow"). Repeat this as necessary until you are ready to learn a little more advanced material.
