In three instances the editors Elisabeth Weinzierl and Edmund Wächter have chosen to base our new editions on the first editions. Original manuscript scores, manuscript copies and alternative versions have only been consulted for potential clarification of editorial queries. The Pièce of 1910 has only survived as an original manuscript, which has been reproduced here as faithfully as possible.

These four pieces are individual works, though they can be performed together as suites of two, three or four movements where required.
