Apply Gypsy Reharmonization of standard 2-5-1 progressions
to give a much more authentic sound a la Rosenberg/Lagrene
When you apply these reharmonized 2-5-1's to a Gypsy Jazz standard it sounds way more authentic and less schooled.
The Rosenberg Trio and Bireli Lagrene often use these alternate changes in many different tunes. The examples I show include Bossa Dorado and All of Me but you can apply them anywhere you have a 2-5-1 progression which is nearly every song in Jazz!
