How To Play I Walk The Line by Johnny Cash
In this lesson I show you how to play the Johnny Cash classic, mainly from the perspective of Luther Perkins great electric guitar part. There's so much you can learn from this song: how to play rhythm guitar in the classic bass note/strum country style; how to connect chords with walk-ups and downs; the names of the I IV and V chords in 3 of the most common keys; how key changes work.
The lesson is based on the original and probably best-known 1956 recording of the song. Cash went on to re-record the song on a number of occasions and it's interesting to check-out the differences between the various versions. The 1964 version is faster and there are some definite changes to the guitar part, particularly in the way Perkins walks up and down between chords. Also great is the live at San Quentin recording, but guitar on this is played by Carl Perkins (no relation) in a quite different more twangy style.
I've written out the intro below. I think it's worth learning this intro note-for-note as Perkins plays it, since it's such an iconic part. If you'd like a PDF of the entire song you can download it here. I suggest that for the verses you use the written part as a guide, and make it your own by varying the movement of the bass line and the right-hand strumming. As I explain in the video, it's actually quite easy to make sense of the key changes if you think in terms of the movement of the I IV and V chords. Each verse has the same progression: V, I, V, I, IV, I, V, I. We start in E, walk up to A, walk up again to D, then walk back down to A, and finally back home to E again.
