Self-control of performance of actions as a condition for successful learning music and performing arts

In article there is a speech about training musical tool in performance on the basis of observance of regularities of processes: 1) coordination of game movements; 2) action of attention - external and internal; 3) reflections in a sound of emotions of the performer; 4) self-checking; 5) conditions of expediency. Today such observance isn't present. Moreover, in scientific literature the insufficient attention, despite need of real coordination of each game movement according to the text, the accounting of features of action of attention in two modes - perceptions and representations braking each other and influencing memory, the emotions which - are exclusively anticipating of self-checking "on a full approximate basis", performance of conditions of expediency is paid to this question. Meanwhile the success in training in tool performance completely depends on that, how game actions correspond to the structures of these processes, laws and the principles of self-government which objectively developed as a result of evolution by actions.
