Take a simple progression with say 2 chords :).Cmin7/ Eb min7.Learn how to phrase over this simple structure by understanding the notes that make up each chord and the fact that these notes will be separated by minor 3rds,all of them.Now using the scale chart that I have posted please look at the options needed to phrase over min7 chords. Starting with our favorite minor pentatonic scales that made Slash a millionaire,you will see that over a minor 7th chord the pentatonics that can be used will be of the 1st,2nd and 5th degrees. i.e for Cmin7 you can use C,D and G minor pentatonics.Try these options out and mix them all over the fretboard.For Ebm7 you have Eb,F and Bb.Use all these devices to make some really cool ideas emerge with string skips etc. Please plot each of these scales on your fretboard charts.
