"Vom Himmel hoch, da komm ich her,
ich bring euch gute neue Mär,
der guten Mär bring ich so viel,
davon ich sing'n und sagen will."
Martin Luther (1534)
Four years ago, Sietze de Vries (NL) improvised some very beautiful variations on this German Christmas tune.
Last year, I did a recording of my transcription with the Schnitger-organ Steinkirchen (by OAM):

For this season, I revised the score and did a new recording, with the amazing Ahrend-organ Regensburg (by Pipeloops).
The revised score is attached for free use, with kind permission by Sietze de Vries.
