Final answer:
Gesture drawing captures the main visual and expressive characteristics of a form, essential for art education and preliminary sketches.
Step-by-step explanation:
The type of drawing described in the question is gesture drawing, which captures the essential form and movement of the subject rather than the details. This technique is often used in art to quickly record the main visual and expressive characteristics of a form. It's a fundamental exercise in art education that helps students develop hand-eye coordination, and it's also utilized by artists as preliminary sketches for more refined artworks. Gestural drawing is valued for its ability to capture the dynamic essence of a subject and can be considered a collectable art form by itself.
