Watch the Half Step Below: Over Major online guitar lesson by Rob Garland from The Guitarist's Pentathlon

Against major chords sometimes I like to play the minor pentatonic scale a 1/2 step below the root. This moves the sound of the scale away from it's traditional blues/rock roots, creating some haunting note choices for melodic playing. In this example when playing over a BbMAJ7 chord, I am using Am pentatonic because the root note of the scale A is a 1/2 step below the chord root Bb.
