Wieniawski gave the Opus 10 studies (as well as Opus 18) the title ''Etudes-caprices''. On the one hand, this suggests that the pieces were intended as exercises in violin technique; on the other hand, it brings to mind Paganini's collection of caprices, in which the didactic character of the pieces takes an artistic form. As a result, the Opus 10 ''Caprices'', similarly to the Paganini set, can also be performed in concert. Thus, Wieniawski clearly had two aims in mind: that tha violinist attain the highest level of thechnical mastery, but also that the compositions be performable as virtuoso concert pieces.
