The variations are grouped by key and, within each chapter, are placed in order of difficulty. In so doing, the composer offers, as piano teacher Erika Becht writes, ''two ways for teachers and pupils to know and try out the many musical and technical variations (such as augmenting, diminishing, canon, melody pairs, etc.). This can be done within the same key, in order of difficulty, or by using the scope of the music to find the right degree of difficulty, and advancing through the key signatures, so developing pupils' ability and sense of security in reading a score by playing in various keys.''
