👉 Interest sounds are the subtle, rhythmic vibrations and tones that occur when an object or surface is being manipulated or examined by someone with a musical ear, often providing insight into its material composition, shape, and texture. These sounds can be heard when gently tapping an object lightly, like a pencil on a piece of paper, or when listening to the creaks and groans of an old wooden floor, revealing the history and character of the material beneath.
