Here's how to play Running Down A Dream by Tom Petty.
This has a very easy 1 string guitar riff that is great for even total beginners to learn - it even uses just 1 finger!
We than also look at how to play the rest of the song, which is more at a late beginner/ early intermediate level and includes power chords and palm muting, making the full complete song more at a grade 2 level.
