Two great swing tunes to learn from the Beatles are “When I’m Sixty Four”, on the Yellow Submarine album and “Honey Pie” on The White Album Disc 2.

One of the coolest things about gypsy jazz are the long lines that players create. In standard jazz guitar you will see long lines but they are often localized to a position and they don’t travel.
Gypsy jazz players are often thinking far ahead and then traveling across the fingerboard. If you need to travel from the Dm 5th position all the way up to the Dm 10th or 12th position you could use a long line like this one to get there and then play a statement at the end to resolve it. (This needs to be played very fast usually)

|————-4-7-|-5————-|—————-7-10-|————-|
|———–6—–|—6———–|————–9——|-10———-|
|——-4-7——-|—–7-4——-|———7-10——–|—-10——-|
|—3-6———–|———7—–|—–6-9————-|——-12—-|
|-5—————|———–8-5-|-5-8—————–|———-12-|
|—————–|—————|———————|————-|
This is one example of a few that I could come up with. This is the first long line pattern I ever discovered. In the first bar its a diminished (in the minor shape), the second bar is a minor6th arp, the 3rd bar is back to a standard diminished run, and finally it ends on the Dm arp. I could even go further by playing a minor 6th in the 12th position and then a diminished again to get even higher.
If you sync to the rhythm in 8ths, 12ths or 16ths you can keep the line going forever and it creates a neat sound. As the line flows you can follow and manipulate the diatonic tension over the chords as they change. Some other arps that I will use for traveling the fingerboard are the harmonic minor and the stacked pattern runs (that I talked about earlier this year).
NOTE: Of course you could add approach notes to these pattern and alter them and improve them a little. I am always searching for better lines and variations. In the first bar you notice that the diminished hits the B string on the 6th fret. If you add leading tones to that arp, then you have the full octatonic diminished and the leading tone on the B string is at the 5th fret which is a nice fit with the harmonic minor.
