What is one common instrument used for practical demonstrations in the MoCA Music Practice Test?

The piano is a common instrument used for practical demonstrations in music assessments like the MoCA Music Practice Test because it provides a clear visual and auditory representation of musical concepts. It is versatile and can illustrate a wide range of musical elements such as melody, harmony, rhythm, and dynamics in a way that is easy for both the performer and the listener to grasp.

In addition, the keyboard layout allows for intuitive exploration of music theory concepts, such as scales and chords, making it an ideal tool for demonstrating musical techniques. The piano's ability to produce both melody and accompaniment simultaneously also supports advanced music skills, making it a frequent choice in various teaching and assessment scenarios.

Other instruments may be better suited for specific types of demonstrations or genres, but the piano's broad applicability across styles and its foundational role in music education make it a staple in practical demonstrations.
