How to hold pencil while drawing

The video tutorial explains two primary pencil grips for sketching: the tripod grip and the overhand grip. The tripod grip, similar to a writing grip, is ideal for detailed work due to its precision and control. However, it can lead to stiff drawings if overused. The overhand grip allows for broader strokes and is more suitable for filling larger areas, utilizing shoulder movement for a wider range of motion. The tutorial encourages using both grips in a single drawing to achieve a balance between detail and fluidity.

Explain how the overhand grip differs from the tripod grip in terms of motion and control.

Why is it recommended to use both grips in a single drawing?
