Other manuscript sources attribute this piece to Johann Pachelbel. Johann Gottfried Neumeister however attributes it in his collection to Johann Michael Bach. This piece can also be found in manuscript Mus Ms 30439, where it differs in little details from the version in Neumeister’s manuscript. The version from manuscript Mus Ms 30439 can be found here. Since Neumeister was not the best scribe, it’s possible that the differences in his manuscript with the version in manuscript Mus Ms 30439 are acutally transcription error’s from Neumeister.
The recording was done on the sample set of the Bader-organ in the Walburgiskerk in Zutphen by Sonus Paradisi for Hauptwerk.
