Practice Technique 31: Synchronization Between Notes Of The Two Hands.
April 25, 2017
Sometimes while we are performing our hands can get out of synch with each other – sometimes for a note or two, sometimes for longer.
There are two ways of preventing that from happening. One has to do with ‘pulses’ coming down both arms as if together they formed but one arm. The other, which I describe here, is to choose periodic locations, perhaps once in each measure, preferably not their first beat, where we can do a quick check-in with our ear to see if the appropriate left hand notes start at the same moment as the appropriate right hand notes.
When that moment comes in a measure, we should take our attention away from hearing the flow of the sounds in one or both hands, and redirect our attention “vertically” (on the score paper), to the momentary sound of the ‘chord’ formed by the combination of whatever notes the left hand plays at that moment plus whatever notes the right hand is playing at that same moment.
It is the principle of a ladder. Without periodic, horizontal cross pieces, or rungs, the sides of the ladder will fall apart. Only the rungs keep them together. So, in piano playing, without periodically directing our attention to the momentary sound of the “chord” (or “interval”) formed by the two hands at a specific moment, the hands will fall apart.
