In Klára Somló's étude collection, the main focus is on position shifts, with exercises covering the span from first to fourth position. In addition, various bowing techniques - such as arpeggio, legato, and mixed bowings - as well as left-hand techniques, including double stops, chromatic passages, and harmonics, are also addressed. The collection is complemented by the musically demanding works of Kummer, Lee, Dotzauer, and others. The volume is suitable for the third or fourth year of cello study.
