stochelo plays this all the time ie on Chicago from the Samois 2003 recording (it's inspired from django's war/post war time period):
it's over an F chord....
e-17-12------------------------------------
b---------13-----------------------------
g-------------14-------------------------
d-----------------14-12-12-------------------
a--------------------------------------
e--------------------------------------
8th notes throughout cept the before last note which is a quarter note... giving the last note a syncopated accent....
this is coming from an Fmaj7 shape: x x 15 14 13 12....
notice it's actually an Am arpeggio (minus the D).... so if you're smart and careful about it, you can play Am ideas over F chords, and F ideas over Am ... this music and others are full of enharmonic symmetries
