Watch the Outside Sound: Over Minor online guitar lesson by Rob Garland from The Guitarist's Pentathlon

Here I'm creating a simple rhythmic pattern using Gm pentatonic against a Gm7 chord then stepping outside of the scale moving up into Abm for a moment to create tension. After I return to the Gm pentatonic I continue playing to re-solidify the sound of the scale against the chord for a strong resolution.
