Now it’s time for the expanded blues scale, the one most commonly used in progressive blues …
E|-----------------------------------------------------------------5--7--8--9--10--12-- B|-----------------------------------------------------4--5--7--8---------------------- G|--------------------------------------5--6--7--8--4---------------------------------- D|--------------------------4--5--7--8------------------------------------------------- A|-----------4--5--6--7--8------------------------------------------------------------- E|--5--7--8----------------------------------------------------------------------------
If you want additional possibilities that sound blues, I think that Melodisk molls 3rd mode, the Dominant Lydiska scale, also known as the harmonic scale, works great. Here it is;
E|-----------------------------------------------------10--11-- B|-----------------------------------------10--12--13---------- G|---------------------------------10--12---------------------- D|------------------9--10--12--13------------------------------ A|----------10--12--------------------------------------------- E|--11--13-----------------------------------------------------
