Jam chord progressions
Playing and jamming difficulties...HELP ME!
Don, you've gotten some good advice here. As Robin has pointed out, the main keys for folk music are C, D, G, and A, and Skip has explained how to figure out the important I, IV, and V chords in those keys. You can use any chord chart, such as those Stephen Seifert makes available , to learn how to play those chords. You should also be aware of how versatile the barre chord is. I assume you can count to 7 and you know the alphabet.
If 000 is a D chord, then 111 is an E chord, 222 is an F (really F#) chord, 333 is a G chord, 444 is an A chord, 555 is a B chord, and 666 is a C chord. Then we start over with D again at 777. Until you learn more chord voicings, those are safe places for you.
Personally, I prefer to approach this by using a capo, which enables me to play in D, G, and A out of a DAd tuning, and then tuning down a step to CGc to play in C. Then I only have to learn the chord positions for one key but they will work in the others. What I mean by that is that 002 is a D chord when tuned DAd, a G chord with the capo at 3, an A chord with the capo at 4, and a C chord when tuned CGc. So I consider that a I chord rather than remembering four different chord names. The same with the 013. That's a G in DAd, but a C with the capo at 3, a D with the capo at 4, and an F when tuned CGc. I could memorize all that or I could just think of it as a IV chord. I could go on, but hopefully you see my point.
I explain this approach in a document I've attached which was written for a different but related question, and also includes a transposition chart for the major keys. And you can see me demonstrating how to use a capo to move to the keys of G and A this video here .
