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.
