Bow Direction
Changes - Circular Motion in the Bow Stroke
As the basic bow stroke becomes
more refined, the bow should not travel on a flat plane in a static
"back and forth" motion. Rather, the angle
will change slightly from downbow to upbow, and the shape
traced
by the
bow
hand
will be an ellipse.
A good way to introduce students
to this concept is to begin with large circular (elliptical) motions.
Have the students play string crossings on open strings as shown in this
video. Note the bow hand of the cellist, and the elliptical shapes
it draws.
For example:
Down bow D string Up bow A string
Down bow A string Up bow
D string
