Which knowledge category would a skilled pianist rely on primarily during a performance?

A skilled pianist primarily relies on procedural knowledge during a performance. This type of knowledge involves the ability to perform tasks automatically and efficiently without needing to consciously think about the steps involved. For a pianist, this includes muscle memory, motor skills, and the ability to read and interpret music seamlessly while executing complex finger movements on the keys.

Procedural knowledge is often acquired through practice and repetition, which allows the pianist to dedicate their cognitive resources to interpretation and emotion in their playing rather than on the mechanics of playing itself. This distinction is crucial in high-pressure performance situations where speed and fluidity are important.

While declarative knowledge refers to knowing facts and information, such as music theory or the history of pieces, it is not the primary focus during an actual performance. Contextual knowledge may pertain to understanding the environment and audience during a performance but doesn't directly influence the mechanics of playing. Conceptual knowledge deals with abstract ideas and principles, which, while useful for understanding music, do not directly impact the physical act of performance. Therefore, procedural knowledge is indeed the most relevant category for a skilled pianist in this context.
