Bow Arm Circles

Introduction

Welcome to Part 2 of my bow arm technique series. Part 1 is The Movements of the Bow Arm and I recommend that you watch that first. The circular motions in the bow arm are related to other technique so I recommend watching the linked articles and videos on this page for more information.

In this segment, we delve into the art of changing directions with your bow arm to achieve a smooth, relaxed, and efficient motion. The focus is on two specific movements: a circular motion at the tip, engaging the forearm and upper arm, and a circular motion in the elbow while playing at the frog.

The Motions Involved

The circular motion at the tip is essentially a micro version of the motion used for string crossings. Once you’re comfortable with string crossings, this circular motion at the tip will become much easier. It involves two key movements:

• The Robot Wave: Your upper arm swivels in the shoulder socket, which is a ball-and-socket joint.
• The Door on a Hinge: Your forearm acts as a hinge at the elbow, combining with the shoulder movement to create the circle.

Practicing these motions separately and then together is recommended.

Circular Motion at the Frog

In the video please observe the circular motion made by the elbow at the frog. This motion needs to translate subtly into the hand and fingers. As the elbow rises the hand pivots in a pronated direction slightly, and as it drops it pivots in a supinated direction slightly. This requires a loose bow hold where each finger, including the thumb, has its pivot point on the bow.

The Importance of a Loose Bow Hold

A loose bow hold is crucial for this technique. If your bow hold is too rigid, raising your elbow will directly affect the bow, causing a string crossing. Learning to pivot and rock your hand back and forth (pronating and supinating) while maintaining your bow hold is essential for this technique.

Conclusion

By understanding and implementing these circular motions at the tip and frog, you can significantly improve your bow changes.

Keep in mind that these two circular motions are related to other techniques:

• The circle at the tip is similar to the motion used in string crossing.
• The circle at the frog necessitates a loose bow hold.

Together, they form a comprehensive approach to smooth bow changes, especially beneficial for those who tense up during direction changes.

Stay tuned for more videos and articles, and happy practicing!
