In Gaston Blay's edition of the 60 studies, published by G Schirmer, the following encouraging preface is provided:
'The study of violin presents certain difficulties for beginners [that] frequently cause a sudden abatement in the pupil's zeal and ambition, even before [the student] 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. If practised carefully and intelligently, [these etudes] will serve as a solid foundation for the technique of any player ambitious to become an artist.'
