Ah, er, I am not actually flamenco player, though flamemco is one of the kinds of music that I listen to and lift from--I have played Russian gypsy music and some Hungarian and Romanian stuff, which is where I fine-tuned my tremelo--Also, so that no one gets the wrong impression, I am not really performance grade gypsy-jazz player--

My guitar teacher was a cohort of Barney Kessel(who is a Django fan) and though there is a high correspondence between my repertoire and the Django repertoire and though I do use fuller versions of the Django chords for rhythm, and can play three finger scales, I usually play in the "random jazz" style--

As regards to teaching, though I haven't taught gypsy-jazz, I think the place to start is by learning how to play a group of six to ten circle of fifth jazz standards using the Django type chords, then moving on to learning to play the melodies from scale positions--after that is down pat, you could move on to using the tricks andpolishing up the style--
