2009 is Mendelssohn’s anniversary year and this has occasioned us to publish in addition to the already existing “Songs without Words” nearly all of his piano compositions in two new extensive volumes (HN 860 and HN 861). All of the works (see Contents) have been meticulously revised and extensive commentaries reflect the latest in scholarly research. Thus we are able to offer a comprehensive Urtext edition of Mendelssohn’s piano works that is unique in this form.
