|Advanced Guitar Songs|
To learn them it's easy to start with the melody line and then move on to the chords and more difficult aspects. These more advanced songs are a good way to work on chords and individual lines at the same time. Take The Beatles' "Yesterday" for example: this song is recognized everywhere and has a beautiful simple melody line that works wonderfully all on its own and can be accompanied with simple chords if the player chooses.
However, the harmonic accompaniment that goes with the original song is very complex and much more advanced and difficult. Another nice perk of starting more advanced playing with these types of songs is that they are usually available in several different keys so you can pick the one that is most comfortable for you.
