"When first playing Für Elise, one's counting tends to lose accuracy because of the considerable variation in cognitive demand: i.e. beginners tend to play it unevenly."
Is this not true of so many actions?
"...considerable variation in cognitive demand:" These words could be applied to many actions which are taken for granted and which are considered simple actions once a person has reached a certain level of achievement. Therefore, cognitive demand is not considered nor the considerable variation as the action is no longer considered to be one which is so demanding to the person. So, for the achievers, 'walking' is a simple action which does not need much thought - yet, this is not true!
ena, I stated that the analysis of this area (music) is deep and wide. When I typed my words, I was only touching the surface and chose not to go into detail. When I spoke of a new introduction to a particular time scale, I was referring to a piece of music of equal length to previously played pieces of music. Of course, stages are applied when learning to play an instrument, whether these stages are guided by a tutor or oneself.
To really go into the depths of this topic; to offer each opinion and discuss each opinion would possibly take a time period of considerable length. In other words, far too long.
