A tuning that allows you to play every major and minor chord with 2 fingers?

[Josho]

I was watching an interview with Bob Brozman from the past and at about the 5:00 mark he mentions a tuning where you can play every major and minor chord with 2 fingers.

Would anyone happen to know what that tuning is? And what positions for the fingers are used with each chord?

In the video it looked like he was only using the top three strings.

He's using open G tuning D G D G B D low to high.

The major and minor stuff he does is using only two strings 1st and 3rd. Then he's running up and down the G major scale harmony.

D|--5---7---9---10--12---14---16---17----------------------------------------|
B|---------------------------------------------------------------------------|
G|--4---5---7---9---11---12---14---16----------------------------------------|
D|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|---------------------------------------------------------------------------|

If you tune the guitar to G minor (low to high D G D G Bb D) then you can play minor chords by barre-ing all 6 strings, major chords by adding a finger to the 2nd (usually B, now Bb) string.

Note that the root will now be from the 5th (usually A, now G) string, and the lowest string will sound a 5th below that. Learned a lot about this tuning from John Renbourn songs.

He may be speaking of G

Sounds like open G that he is playing. Don't agree with two fingers to form every major and minor chord as practical or very useful. Nice dream though.
