Dotzauer’s 113 etudes are divided into 4 volumes. Schirmer offers Volumes 1 and 2 only. Volume 1 includes Nos. 1 – 34, edited by Klingenberg, Notes, slurs, fingerings are identical to the IMC edition, but this thinner white paper may not provide the sharp contrast some cellists prefer. Also there are annotations for Whole Bow, Upper Half, Lower Half, etc. in this edition.
