Very few educational books can provide a long career without substantial alterations; Arban's famous method, however, is one of them, and so far, it has proved its worth by forming several generations of brilliant virtuosos and eminent professors, thus proving the exceptional values ​​of its pedagogical qualities. The excellent principles that form the basis of this admirable work remain immutable, but some details of execution, which the composers of the past had not imagined, were innovated later and are now common practice.
