To play this song you have to be able to read the Thin E string, B string & G string.
As you can see in the 1st bar the first two notes are eighth notes (two notes every beat). On the 7th and 8th bar there is a tied note, this joins an "A" note across the two bars. This gives the "A" note a value of 4 beats. Remember, this song is using a 3/4 time signature (3 beates every bar).
