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 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 F# 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. If I wanted to get a bluesy vibe, I’d use the D major triad and combine it with the F# diminished triad, as demonstrated in FIGURE 3. Here, the C note is heard as the b7 (flat seventh) of D, implying a D dominant-seven tonality. Now let’s try combining the F# diminished arpeggio with an A minor arpeggio—A C E—as shown in FIGURE 4. The combination of these two sets of notes gives an F#m7b5 arpeggio (F# A C E: see FIGURE 5).
These licks work well over an Am chord, as the inclusion of the F# note, the major sixth of A, implies an Am6, A Dorian–mode type of sound. As you probably have noticed, all of these arpeggios are played on the top three strings, and I often like to incorporate sweep picking when using arpeggios like this.
FIGURE 6 illustrates a combination of an Em7 arpeggio—E G B D—and a Gmaj7 arpeggio—G B D F#. As denoted in the example, in order to sweep pick these arpeggio shapes
