Half-Shell Voicing

3 – R – 7

Prove it — just do the practice exercise.
CMaj7 Half Shell
E (3)C (R)B (7)
The Half-Shell Voicing reverses the shell formula:

3rd on bottom
Root in the middle
7th on top

Very compact — notes are close together. Ideal for the left hand.

Example: CMaj7 Half-Shell = E + C + B
