Dont Studies and Caprices Opus 35 for Viola (Schott) transcribed for viola with preparatory exercises by Max Rostal 

Jakob Dont was an Austrian violinist, composer, and teacher. He is known for his major educational works, with over 50 becoming quite popular. Dont's 'Etüden und Capricen' Op. 35, a collection of studies and caprices, was arranged for the viola by Max Rostal. Rostal added preparatory exercises and variants to the original work. 'Etüden und Capricen' covers various technical demands such as arpeggios, double stops, dexterity, change of position, legato, change of string, types of bowing, trills, and appoggiaturas. As a result, it provides a solid foundation for practising any repertoire.

Jacob Dont was an Austrian violinist (March 2, 1815 to November 17, 1888) who was known for his exceptional talent as a teacher and composer. He studied under the guidance of Josef Bohm and Georg Hellmesberger. At the young age of sixteen, he became a member of the Hofburgtheater orchestra, and later on, in 1824, he joined the Vienna Hofkapell as well. Despite his success as a soloist, he chose not to pursue a career as one and became a professor at the Padagogisches Institut in Vienna. He also taught at the Wiener Konservatorium but eventually had to leave the position due to the prohibition of using his compositions for teaching. Most of his works consist of innovative teaching material, and he is most famous for his 24 Etudes and Caprices Gradus ad Parnassus Op. 35, considered some of the most critical technical studies for the violin. Some of his students include Leopold Auer.
