I'm coming here today, 'cause I need some help to improvise over a chords change that give me difficulties..
Here is the changes in question :
| Gm6 | A7 D7 | Gm6 | Eb7 D7 |
It's a blues / swing / rock song, with mid-tempo ; here is how I see the harmony for now :
We are in the key of Gm, D7 being the V7, A7 being a secondary dominant (replacing iim7) and Eb7 being a tritone substitution for again iim7
What do you think ?
Now, how can I improvise over this ? I have difficulties playing lines that "sounds right", I mean, bluesy on this ; I see also the kind of ii V I implied by "A7 D7 Gm6", but can't really play a jazzy line on this.. ?
Can you help me ? Which scales would you choose on that ? Do you have some records examples of songs with similar chords changes, where I could transcribe the chorus ? (any instrument would do the thing, I'm playing the accordion).
