Altered Run over A7
This altered run uses Melodic Minor scales over an A7 chord. The first measure is G Melodic Minor: G-A-Bb-C-D. This gives us the b7-root-b9-11 of A7.
The second measure is from Ab Melodic Minor: Bb-C-Db-Eb-F. This gives us the b9-#9-3-b5-#5 of A7.
The third measure uses D Melodic Minor: D-E-F-A-B. This gives us the 11-5-#5-root-9 of A7.
The last measure is an E Melodic Minor fragment: G-A-B-C# (after the F from the preceding measure's D MM scale). This gives us the b7-root-9-3 of A7, which is normal tension and helps to resolve the "out-ness" of the previous tones.
