Here's some charts I put together for Gdg and DAd open tunings. The charts give the power chord (which can be used for either a Major or minor chord) and the Major, minor and dominant 7 chords, minus the 3rd. The chords may not sound "complete" without the 3rd, but you should still be able to have a lot of fun with these - and you'll still create a good sound.
I also started on ukulele. Been playing tenor for a few years off and on - I mostly just play chords to songs I find online. In my opinion making the transition to CBG is pretty easy. I just need to take the time to make a fretted instrument now that I'm tired of playing slide.
I hope the charts work out for you,
Does anyone know of any linux programs to make charts like these?
Is this chart for slide on a fret less or just a fretted guitar with fingers?
Here's an AI tool I made for generating chord inversions for any 3 string tuning: http://pbrown.me/cbg.html It's saved me a lot of time!
