The Plane, as you know, is this flat inclined surface that extends from the ground and up, intersecting some point on your body. All of the activity of the golf swing should not disturb the Clubshaft from remaining on this plane. Cocking, Uncocking, Rolling, Turning, Swiveling etc., should all be performed with the Clubshaft remaining flat against this plane. That is called Clubshaft control.

There are various angles of Planes that can be used. Those near the Shoulders can be grouped and named the "Shoulder Planes". Those around the Hips/Waist are called the Elbow Planes.

Swinging, using one plane angle or another, or shifting from one plane to another involves using different procedures to control the Clubshaft for it to remain perfectly On-Plane.

The Shoulder Planes have different reference points (where the inclined plane intersects the body) which correspond to the steepness of the Angle or one of its other characteristics. Each one is named. Square Shoulder, Left Shoulder, Turning Shoulder (type a and b) and Turned Shoulder.

Each Plane may have different performance characteristics as well as different levels of difficulty in achieving consistency. But the Goal is always the same; controlling the Clubshaft.
