So I just had some success, after nearly 6 months of practice--I finally nailed the middle part of 'Rythme Futur.' It is the spot where in Django's version, the clarinet takes the melody. SInce July(not kidding), I've been working on getting that down. I've been doing Stochelo Rosenberg's recomposition. Although it does work on the guitar, it is extremely difficult to nail it at the stratospheric tempo he plays it.
I have yet to perform it at the final tempo yet, and it may well take me another 6 months to a year to do that successfully. But it happened after I had been playing 12-string guitar for a different non-Gypsy side project I am involved in. It really hit home to me that I did it because my left hand has indeed gotten much stronger from playing the 12 string. So I already knew that in order to play Gypsy style swing music you need to have a strong and firm technique....but I guess this was just a reinforcement of that. I recently had a mini-lesson/jam with the great Stephane Wrembel and he told me you need a very strong LH, and he looked at me and played a C major-scale and said "Hanon."
Anyways, I don't know what all this rambling might be good for exactly, but I think it may point out something that is obvious to some of us that has been playing the Django style for a while but hit a wall. Do your 'Hanon," get a job lifting boulders, or play a lot of 12-string guitar...something that will make your LH strong. Then when you really do play on the gig---your physicality will disappear and your music will flow through.
Hope everybody had a great weekend,
