Introduction

One of the basic principles of healthy and natural playing of stringed instruments is the connection of arm movement with the balance of the whole body. Nora Krohn refers to this principle as "moving through the fulcrums of the feet and sit bones". It is a simple but essential mechanism that ensures that the body responds to hand movements naturally and without isolation. This relationship between body and instrument is key to both effective technique and recovery from focal dystonia.

The natural physical logic of movement

Just like in everyday life, even when playing the violin or viola, the body should maintain movement in accordance with physical logic - that is, as it naturally adapts to the direction of the arm and hand. For example, if we clean the window or wipe the table, the torso automatically tilts forward or backward according to the position of the hand. Regardless of whether we are standing or sitting, the body balances on the support points - on the feet or sit bones. This principle ensures stability, flexibility and fluidity of movement without the need for conscious control.

Experiment: cleaning windows

Krohn uses a simple exercise: imagine we are cleaning a slanted window. Our body instinctively tilts and aligns according to the movement of the arm without thinking about it. However, if we stop this natural sequence of movements - for example by fixing the trunk - we immediately feel that the movement of the hand becomes limited, inefficient and tiring. The arm begins to compensate for the lack of space and tension is created. The same mechanism applies when leading a loop - if the body does not follow the arm, the shoulders become overloaded and fluidity is lost.

Transfer of the principle to the right-hand playing

When playing with a bow, the hand acts as an extension of the arm and the whole body should follow this movement. When the player maintains the connection between the bow movement and the balance of the body, a natural distribution of energy is created. The body gently sways over the fulcrums, promoting fluidity and confidence in every part of the slide. This principle helps to prevent fatigue, especially during slow or quiet passages, when tension in the shoulders or wrists often appears without active work of the whole body.

Left hand movement

For the left hand, the movements are smaller, but the principle remains the same. Krohn explains that when shaking hands or receiving a cup of tea, the body naturally balances back and forth according to the direction of the arm's movement. As the arm approaches the body, the trunk leans back slightly to create space; as the arm moves away, the body follows. If we suppress this natural movement, unnatural tension and loss of coordination arise - the body seems to "bump into itself".

Practical exercises

• Wall exercise: Stand with your feet hip-width apart and place your hands on the wall. Slowly move your hands up and down and watch your body adjust itself. The goal is to perceive that the torso and arms form a connected whole.
• Bow and balance: Take the bow and simulate a slow pull on the string without playing. Observe whether the body reacts to the direction of hand movement. If it remains stiff, try allowing natural balance through the feet or sit bones.
• A cup of tea: Imagine receiving a cup of tea from someone standing in front of you. Feel your torso gently shift back and forth as your arm moves. Transfer this simple principle to your left-hand playing.

Consequences for body and brain

Movement through the support points of the feet and sit bones connects the whole body into one unit. Thanks to this, the movement becomes efficient, flexible and natural. When the body functions as a unified system, the brain stops sending the conflicting signals that often cause dystonic symptoms. At the same time, this principle helps to restore security and peace – because the body again moves in accordance with gravity, not against it.

Neuroplasticity and balance awareness

Each exercise based on movement through these fulcrums strengthens new nerve connections responsible for coordination. This process, known as neuroplasticity, allows the brain to relearn from strained patterns to natural and efficient ones. The player thus learns to trust the body, instead of trying to control the movement consciously. Balance thus becomes not only physical, but also psychological stability while playing.

Conclusion

The principle of movement through the fulcrum points of the feet and sit bones is the basic building block of healthy playing of stringed instruments. It allows the body to react naturally, transmit power without tension and maintain freedom of movement in every situation. For musicians recovering from focal dystonia, this approach is a way to re-establish the connection between body and music – with ease, confidence and balance.
