Dotzauer's études have been part of the standard repertoire in cello lessons for generations. Our new edition of the 12 Études Op. 107 follows the original sources and contains the original text. While the Dotzauer études are usually only available in selected editions today, opus 107 is edited here in its entirety, as conceived by the composer himself. Notes on studying and on the performance practice (dynamics, vibrato, change of position, ornamentation, bowings) make the new edition an ideal reference edition for music lessons. The Études Op. 107 contain some of Dotzauer's best-known études of medium difficulty, in the 1st to 4th position and with major technical problems such as arpeggios, velocity, string crossings, slow and fast bowing, double stops, two-part playing, etc.
