33 Johnny Cash Guitar Chords - Tutorials
Below are 33 songs I've covered so far and 30 have free chord sheets available in pdf format that you can download. Eventually I'll get those other 3 sheets in place.
You'll find that many of Johnny Cash songs are three chord songs, especially the earlier recordings. And with Johnny's low vocal range, E, A and B7 were favorite chords.
I have been toying with the idea of posting chord sheets into web pages as you see below. Pdf files are at least downloadable but with 2 browser windows open, one could play along with the demo while having the chord web page open as well. I haven't decided yet on the web page format as it's quite a lot of work.
