The most direct way to describe the essence of the concept and benefits of these exercises for
the aspiring violinist is to simply quote from Rachel Barton Pine and Dr. Roland Vamos:

“Roland Vamos’s double-stop exercises fill a
void in the literature of technical exercises for
violinists and violists. Today there are many
classic books with thirds, sixths, octaves, etc.,
by such composers as Schradieck, Ševˇcik,
Flesch, and Dounis. However, none of these
wonderful collections features a systematic
series of fixed double-stops that enables the
aspiring violinist or violist to practice and master
every possible combination of finger patterns
across two strings without shifting.”
—Rachel Barton Pine

“So what exactly do I hope the student that
carefully studies these exercises will accomplish?
Perhaps the most important accomplishment is
the development of a strong left hand that is set
up so that the fingers rise and drop consistently
landing on the same part of the finger. The first
joint of each will hopefully develop strength
and flexibility while the thumb gently supports
the side of the neck without tension. These
exercises, when practiced slowly and carefully,
should also help to develop a keen sense of
pitch and intonation.”
—Dr. Roland Vamos
