What is the primary function of a sketchbook for an artist?

The primary function of a sketchbook for an artist is indeed as a tool for experimentation, practice, and recording ideas. A sketchbook serves as a foundational tool that allows artists to explore their creativity without the pressures associated with creating finished pieces. Artists use sketchbooks to try out new techniques, develop concepts, and jot down spontaneous thoughts or visual ideas. It is a safe space for them to make mistakes, play with forms, and discover their artistic voice without the constraints of a polished final product.

In this way, a sketchbook is integral to the artistic process. It can capture the evolution of an artist's style and technique over time, documenting their journey as they refine their skills and ideas. While it may sometimes include personal reflections, the main purpose revolves around artistic exploration and practice rather than serving as an exhibit for finished works or a strict archive of completed projects.
