Composer's Note:

The study of the violin presents certain difficulties for beginners which are frequently the cause of a sudden abatement in the pupil's zeal and ambition, even before he has mastered the first rudiments.
The blame for this is commonly laid on the teacher, who is called incapable or negligent; losing sight of the fact that the pupil began his studies without the slightest notion, not merely of the difficulties to be encountered, but also of the regular and assiduous industry indispensable for surmounting them.
It is important therefore, to smooth these first asperities by showing their utility and making them agreeable; to this end my Violin Method was published and the present Exercises have been written, which latter may be considered as forming a supplement to the former.
If practiced carefully and intelligently, they will serve as a solid foundation for the technique of any player ambitious to become an artist.
