Watch the Shell Voicings online guitar lesson by Frank Potenza from Jazz Harmony Handbook

In this lesson, we'll look at shell voicings that are made up of the 3rd and 7th of the chords, typically referred to as the "guide tones". These are a simple but powerful way of playing the essential harmony in a stripped down, bare bones sort of way. They provide a concise voice leading strategy that serves us well in playing blues progressions and much more. Notice how I often slide into them from one fret below to add nuance and vibe.
