I wrote this short little jazz bit for the contest. Syn's tip I use comes from lesson 106
"For example, each time you come across the "V" chord when you're playing to the backing track, play a different concept we've discussed over it each time. Let's say you play a Super Locrian over it the first time, next time play a C minor arpeggio over it(since we are in "E"). The next time play your Tritone Substitution but arpeggiate it meaning that you would play an F7 arpeggio. Next play a C minor9 arp and so on and so forth."
I went a little lenient on it and just took it as use a different idea each time you come across the V chord where I mixed some of Syn's suggestions with my own.
The 2 V chords in the chord progression are F#7 and E7.
Over F#7 I used F# mixolydian, a john mayer lick, super locrian and a tritone substitution(C#7 arpeggio)
Over E7 I used Double harmonic major scale, phrygian dominant scale, dominant diminished and a gypsy jazz lick I like to use.
