Question

Quizplus · Accepted Answer

The cerebellum is responsible for coordinating and controlling movement, including the fine motor movements required to play the piano. Therefore, it is the best choice for the portion of the brain that controls and coordinates piano playing. The thalamus and diencephalon are involved in sensory processing and relaying information, while the medulla oblongata regulates autonomic functions such as breathing and heart rate. The corpus callosum connects the two hemispheres of the brain and is not directly involved in movement control.
