The System: Four Final Upgraded Shapes for the B-String

Here's our final framework. Four last shapes to give you a ton of confidence and control over these advanced harmonies, letting you play them all across the neck.

The B-String Major 7 Shape. Your "jazzy," "sophisticated," and "dreamy" chord for this final position.

The B-String Dominant 7 Shape. The ultimate "tension" chord that demands resolution.

The B-String Minor 7 Shape. Your "cool," "soulful," or "introspective" chord.

The B-String Half-Diminished 7 Shape. Your high-tension, "unstable" chord for maximum drama.

The system has not changed: Find the root note of the chord you want on the B-string, and apply the correct upgraded shape. That's it.
