Watch the G7 Blues: Chord Tone Licks online guitar lesson by Rob Garland from Melodic Soloing: Blues Chord Tones
So how did I connect the 3rd's & b7th's? I'm seeing a combination of the chord voicings and arpeggios. Play through the arpeggios and look at how my licks use the chord tones with bends and additional tones to spell out the harmony of the chords. I'm repeating the main theme and leaving space, standard blues ideals.
