First edition of a reconstruction, reconstructed and edited by Alexander Ferdinand Grychtolik, RISM: See preface. J. S. BachÆs cantata "O angenehme Melodei" has only survived as a fragment. It can however be reconstructed because we have the wedding cantata BWV 210 "O holder Tag, erwünschte Zeit", which is a later parody version of it. The text and three recitatives are completely different from the wedding cantata. This first edition of a reconstruction by the harpsichordist Alexander Ferdinand Grychtolik provides a possibility of presenting this so called "sponsor cantata" in a form suitable for practical use in todayÆs concert life.
