Diminished tapping arpeggios has the exact same technique as any other tapping arpeggios, with the main difference being that the consistent pattern lends itself very well to position shifting, and sliding up and down the neck. Pay attention to how I am shifting position during the sequence, and try to come up with different variations to this, mirroring my patterns, or finding your own ideas. You will find that many of my tutorials contain similar sequences, but usually slide on different notes, or with different fingers, and especially use different rhythmical contexts (which you can get a taste of in Part 6).
