The most important step in bowing your instrument successfully is developing an excellent bow hold.
Each specific finger location has a defined purpose!
Once mastered, they then work together as in a factory, a bow mechanics factory.
In a factory, assembly-line workers and supervisors perform individual tasks on assorted machinery, and their combined functions then produce the end result, the product. In the case of Sound Production, the Bow-Hand and Bow-Arm work individually with a bow, and they combine jobs, just like a factory.
Factories produce a product. String players produce beautiful sounds as the product!
Each finger is responsible for several tasks, individually and collectively. When combining specific tasks, you create a Bow-Hand Team!
