“A greatly shortened version of the Preface appears in English. The two volumes of songs now published contain a total of 29 songs, in a style similar to that of her brother.” (South African Music Teacher)

Animato:
“The very carefully edited volume is, pleasingly, furnished with an especially extensive and informative preface.”

Schweizer Musikpädagogische Blätter:
“The very extensive and worthwhile preface by the editor, Anette Maurer, discussing biographical and editorial details, deserves particular mention; it is supplemented with facsimiles. The revision report has been carried out with meticulous care.”
