Wild Stringdom with John Petrucci: Combining Triad Arpeggios to Form Polytonal Chordal Allusions

This video is bonus content related to the April 2014 issue of Guitar World. For the full range of interviews, features, tabs and more, pick up the new issue on newsstands now or at our online store.

As I have discussed in previous columns, I often use triadic arpeggio forms within my riffs and solos as a tool to create rich-sounding, poly-chordal sounds.

I’d like to continue in that vein in this month’s column by presenting different ways in which to move from one arpeggio form to another, using a series of specific triads that complement one another well.

Let’s start with the triads Fs diminished and D major, as shown in FIGURES 1 and FIGURE 2, respectively.

The F# diminished triad is built from the notes C, F# and A, and the D major triad is built from almost the same set of notes, D, F# and A. Both FIGURES 1 and 2 show these triads as played in fifth position for comparison.
