Shaking a pencil can be a common habit or a fidgeting behavior that some people engage in when they are deep in thought, feeling anxious, or simply bored. However, there are no specific fields of application where shaking a pencil is used as a deliberate action to achieve a particular outcome.
That being said, there are a few areas where shaking a pencil or using it as a tool for creating art or design can be applicable, including:
Drawing and sketching: Shaking a pencil can be useful for creating various types of line work and textures in drawings, sketches, and illustrations. It can also be helpful for creating loose, gestural marks or quick, preliminary sketches.
Writing and note-taking: While shaking a pencil can be distracting to others, some people find that it helps them focus and concentrate when they are writing or taking notes. It can also be a way to release nervous energy or relieve stress during long periods of writing or studying.
Music composition: In music composition, a pencil is often used to notate music on a staff or sheet music. Shaking the pencil can be useful for creating different types of markings, such as accents or staccato notes, or for creating dynamic variations in the music.
In summary, while shaking a pencil is not typically used as a deliberate action to achieve a particular outcome, it can be useful in certain artistic and creative pursuits.
