Is declaritive memory the category of memory that is involved when playing the piano?

No, declarative memory is not primarily involved when playing the piano. Declarative memory pertains to facts and events that can be consciously recalled, such as knowing the names of notes or Music Theory. Playing the piano relies more on procedural memory, which is responsible for performing tasks and skills automatically through practice and repetition. This type of memory allows pianists to play without consciously thinking about each movement.
