Imagine that the right arm is a garden hose through which water is running. For the water to run in good measure from the muscles around and along the shoulder blade through the arm to the hand and fingers onto the bow, the hose has to stay in such a way that no knots occur. The hose cannot have kinks, especially in places such as the wrist. If there is a kink in the hose at the wrist, the water is going to run out onto the floor. It will not make its way to the fingers where it can sprinkle the flowers of sound on the neck of the violin.
To give another common example of poor posture and how it impairs and impacts sound: the too-high right elbow. Players, in an attempt to achieve their preferred intersection of the arm and bow to a given string, may place their elbows at too high an angle. In general, this positioning is in tandem to a right shoulder which is raised and rounded to the front. This incorrect position of the shoulder can lead to the movement of the elbow being blocked, which, in turn, leads to a very
limited movement of the bow across the strings.
The left side of the body is just as likely to fall prey to bad basic postural habits. For example, letting the scroll of the violin drop low. This not only looks improper and inhibits the full range of movement of the left arm and hand, it turns the left ribs into an accordion-like structure. The natural space between the upper and lower ribs becomes artificially shortened for long periods of time, which, in turn, creates imbalance throughout the muscles of the torso and reduces the ability to breathe freely. (No wonder you feel nervous when you play…).
Another favourite of improper posture which can be seen across the board is the raising of the left shoulder. Raising one (or both shoulders) is a habit that many people adopt—fight or flight, right? But violinists tend to settle into this ubiquitous incorrect position of playing with a raised left shoulder in childhood or, at the latest, as we grow up and the support we require to maintain a comfortable position of the violin between head and clavicle widens. How do we bridge this gap if the shoulder rest we use is too? What if we don’t learn how to successfully play without a shoulder rest? The answer is something our bodies can easily slide into: we raise the left shoulder.
There is hardly a player who does not either raise their left shoulder or push forward in an effort to balance the position of the violin. The domino effect of such a position includes a shortening of the left side of the neck (whilst playing), squeezing the muscles of the upper arm, shortening the functionality of the muscles of the lower arm, and overuse of the pectoral muscles, which in turn, continue to pull us forward long after we have laid our instruments to rest for the day. Interestingly enough, very few pay attention to these gross motor mistakes. Rather, greater attention is paid to the fine motor skills and details of playing — the position of the little finger on the bow, the movement of the third finger of the left hand on the string whilst vibrating, the exact number of millimetres with which we stroke the bow across the string, and the angle of the left hand as we practice devilishly difficult, double-stop passages. But what good does it do to our health and our approach to playing and interpreting, to zoom in on the details when the big picture is literally skewed?
There can be nothing of greater importance than ensuring that great musicians continue to make great music until the very last moment of their lives, living their passion for music until their last breath. We must ensure that we do not cut such objectives short through easily avoided, basic mistakes. Zoom out and observe the complete picture. When we play and teach, let us set the frame of the big picture straight. Our bodies will thank us for it, our playing will ring more true, and we will be in tune with the instruments which give us life.
