Ballistic Movement: the springs of action

"Some movements are so rapid that there is no time to get feedback information from the muscles while they are being executed. A rapid musical arpeggio has to be planned in advance and the whole sequence is launched like a ballistic rocket."

During the second World War experimental psychologists distinguished between movements which were being continously controlled throughout their action and ones which had a ballistic character and could not be modified once they had started." - Jonathan Miller from "The Body in Question".

A rapid musical arpeggio has to be planned in advance and the whole sequence is launched like a ballistic rocket.

The implication for practice is that you have to program your nervous system in a building block approach, so the sequences of movements which make up scales and arpeggios can be "set off" by a single musical thought.

You don't have time to play "note by note".
