Answer:
Figure-ground
Explanation:
As per Gestalt, the 'Figure-ground principle' is characterized as the perception theory in which the people display the propensity of their visual arrangement to segment whether the objects are in the background or forefront. They are able to project if the figure(object) lies in the front or in the ground(background). This is the tendency that is displayed in Anthony's ability to perceive the 'violin's melody despite the louder sound of other instruments.' Thus, he employs this principle of the 'figure-ground' where the figure is the object whose sound is coming and the ground where it is coming from.
