The private
Exists, however, and other discipline.
In an orchestra even the best violinist submits to the conductor, because it as well as the conductor, aspires to that the thing was well executed.
The private who jumps on command, as a rule, not especially cares of efficiency of army.
Any army copes generally fear, and the soldier knows that in case of nonobedience will be punished.
The school discipline can be similar on orchestral if teachers are good, however too often it is discipline of army type.
