These 30 Etuden of Simandl belong certainly  to the  obligation literature of each student. In addition, for the finished  trained bassists this Etudes offer again and again the raw material for  the practice of his existence as musician: They illustrate musically and  rhythmically exactly the material, which one meets again and again as  practising bassist. This revised expenditure was supplemented by the  publisher with different preparings to each individual Etude, in which  the rhythmic-thematic material of the Etudes can be trained in  particular mostly on basis of scales.
