Sometimes there is no minor chord in there.
eg. E G A
Sounds good but has no minor chord. Just notice that E is three half steps away from G which is two half steps away from A
Notice how it conveniently overlaps with the E minor pentatonic scale? The best way to figure this out is to simply notice the 3 tone / 2 tone difference.
If this is the case go crazy with the (in this case) the E minor / G major petatonics / G major scale.
Enjoy!
