Watch the C7 Form online guitar lesson by Brad Carlton from CAGED Dominant
Arpeggios are integral to single note ideas, but here Brad demonstrates their importance when building harmonies and chords. After a demonstration, he stresses running through all of the possible combination of tones to develop a multitude of dominant 7th voicings as well as an aid to help visualize the fingerboard beyond simple finger patterns.
Next, Brad discusses singing the scale tones and note names while running through single-note phrases built from arpeggios. Expanding on this technique, he offers up ideas for developing both rhythmic and melodic motifs to use in improvisations.
