What aspect of instrumental skills does the MoCA Music Practice Test evaluate?

The MoCA Music Practice Test evaluates proficiency in reading music notation, which is essential for performing and understanding written music. This skill involves interpreting symbols that represent musical notes and rhythms, enabling musicians to accurately play or sing pieces as intended. Proficiency in reading music notation is foundational for musicians, as it allows them to access a wide range of repertoire across different genres and styles.

While the other options may involve significant musical skills, they do not focus specifically on reading notation, which is a critical component assessed in the MoCA Music Practice Test. The ability to improvise, compose music, or know various instruments, while valuable skills in their own right, does not directly relate to the understanding and application of music notation itself. Thus, proficiency in reading music notation is the key focus in this evaluation.
