Final answer:
The medium of an artistic work describes its form, which refers to the physical materials and methods used in the creation of the artwork, influencing the content and message conveyed to the audience.
Step-by-step explanation:
The medium of an artistic work describes its form. This term refers to the materials and methods used to create the artwork. An example of how medium imparts meaning is found in the work of Andy Goldsworthy, who uses natural elements like leaves and stones, drawing attention to the environment through his choice of materials. In contrast to terms like tradition, culture, and genre, which refer respectively to the historical practices, the societal influences, and the categorization by style or subject matter in artistic works, the medium is much more focused on the physical composition and the manner in which the art is presented. The medium informs the tactile and visual experience of an artwork and can deeply influence the content the work communicates to its audience. Therefore, understanding the medium helps us to appreciate the underlying message or effect intended by the artist. In essence, as Marshall McLuhan famously said, "the medium is the message".
