You can solo over ii-V7alt-I-VIalt chord progression simply by using minor pentatonic scales.
Take Dm7 – G7alt – CMaj7 – A7alt as an example, you can use Am pentatonic – Bbm pentatonic – Bm pentatonic – Cm pentatonic scales.
| Chord | Dm7 | G7alt | CMaj7 | A7alt |
| Pentatonic Scale | Am | Bbm | Bm | Cm |
So basically, from the ii chord root, you go up a perfect fifth or go down a perfect fourth to find the pentatonic scale to play over the ii chord. Then for each subsequent chord, simply play the pentatonic scale haft step above.
Another way to find the corresponding pentatonic scales over chord changes is
- ii: go up a perfect fifth or down a perfect fourth from the root
- V7alt: go up a minor 3rd from the root
- I: go down a half step from the root
- VI7alt: go up a minor 3rd from the root
