The tritone scale is created from two major triads that are a tritone apart. In this case, I’m using the G and Db major triads that result in a hexatonic scale G-Ab-B-Db-Dn-F and can be used for altered dom7 lines over both G7 and Db7. This scale can be played in position on the guitar using three distinct patterns, or modes. The 1st mode pattern starts on the root of each triad, the 2nd mode starts on the third of each triad, and the 3rd mode starts on the fifth of each triad.

These patterns are based on the arpeggios of the G major and Db major triads, and theyt fit loosely over the top of the modal patterns. In the video, all of the the three note arpeggio groups are played first, and each one starts from a chord tone of G major. The four note groups are all played next, each one also starting from each note of the G major triad. Essentially, the first example starts from the root, the next example starts from the 3rd, and the next starts from the 5th.

Since the patterns are identical for every hexatonic scale, the ones for Db are not played in the video but are written out for comparison.
