Let's talk about bowholds.
A good bowhold is often one of the first things we learn when we begin violin lessons. It can often be difficult at first, since we hold the violin bow differently than we hold anything else. It can also be confusing to remember just what each finger does and their specific job.
Take a look at the photo (excuse my dire need for a manicure), and let's see what each finger does.
Thumb - bent, on top of thumb, on the metal part on the underside of the bow.
First finger - is on FIRST joint (not second!). It is not curled around, gripping the bow. Instead, it is loose, soft, and shaped like an eyebrow.
Second and third fingers - relaxed. Touching the frog. Soft. Covering the frog.
Pinky - round, and on the tip. It rests somewhere near on top of the white circle on the bow. It should not be all the way over by the adjusting screw, but closer to the rest of the fingers. This way it has more of a chance to be bent.
If you are my student, you probably are very used to me ensuring over and over our bowhold is perfect.
Each finger has a specific job, and if all is done correctly, the bowhold helps us produce beautiful tone, allows us to play with a variety of bow strokes, and becomes effortless over time.
There is also a photograph of a perfect bowhold at the beginning of Suzuki Book 1, if you ever need a refresher!
