A musical instrument can be mastered only by acting
This “acting” creates information that addresses at least 3 senses: hearing, sight and touch
The latter is added to the information that comes from the study material
Humans’ ability to process information is limited
Does that mean that study materials designed for learning a musical instrument have to be different (less informative or less concentrated) to avoid cognitive overload?
Or, maybe the motor actions have a separate channel?
