minor pentatonic with bridging
Example 1: Let’s begin with our old friend, the minor Pentatonic scale (A-C-D - E- G). If we look at the intervallic structure, we find tone (two-fret) gaps, between the b7 and root (G-A), the b3rd and 4th (C D) and the 4th to 5th (D E). Our task here is to plug the gap with the chromatic passing tone, or ‘bridge’, between the two stable Pentatonic ‘pillars’. You can hear ideas of this nature in the riffs of Tom Morello and Rage Against The Machine, and the soloing style of rockers such as Slash, Joe Perr y and Steve orse.
