for more options on phrasing on a Min7 chord you can use the minor pentatonic in the 1,2 and 5th degree. i.e. for Amin7 you can play the A,B and E minor pentatonic scales.Also you can play the tones of Gmajor, Cmajor and F major.i.e major shapes on the b3,b6 and b7 degrees. Please forget the fancy modal names just try these sounds in as many positions as possible.Hope you can have some success with these tools :)
