Chaz, "In New Orleans" is one of the few Leadbelly songs I just HAD to learn (I'm not really a big 12-string player). Of course, his big Stella was tuned at least a whole note low, maybe two, so the actual pitch is not the chords you're playing. But it's played in "G". Listen to it a lot so you'll hear all the runs that lead from chord to chord. It starts with a double hammer-on on the A string that goes up and then down, landing on the bass string at G. It goes immediately to a D, then a couple of hammer-ons and a run down to Am. Next runs lead down to E, then it goes to A, then run up to D. Then it all starts over again with the double hammer-on as before, all same pattern, which then resolves to G at verse end. Although it's hard to just play and strum without the runs, the chord pattern seems to be D-G-D, Em-Am, D-G-E-A-D. Hope this isn't too confusing- it's hard to write down for an "ear-learner" like me. Anyway, it is surely one of the best examples of his genius on 12-string.
