Watch the The Irish Girl online guitar lesson by Adrian Legg from Fingerstyle Revisionist: Adagio Songbook
I think this song is very simple and shouldn't give you too much trouble, but there are a few difficult pieces. The first part we'll look at is the intro, with the important thing to watch is the first note is in the bass and ahead of the beat. We'll be trying to "float" it more and not bash down on the beat. You might be encouraged to pull ahead to the beat, so you must be conscious to hold it back while playing.
