Another view. Cool again. Fusing pentatonics give the same result. Learning the one or two note alterations of major scales gives all the other results. (which are within the pentatonic fusions). Understanding blue notes within both major and min pents will expand any POV. Pents give a new guitar player a form of control. All those great arpeggios across the fret board. Moving the pents or arps per chord or per tonal center is a major eye opener. Not to mention, fun. Ex. play an Eb7 over and fuse A7 arp. Sliding or pulling off to a tri-tone makes a gorgeous sound to it's ultimate end. Fusing pents pretty much covers American music in general. Once the rules make sense, breaking them is American. That's even cooler.
