Vom Himmel hoch da komm' ich her

As Joachim Scheufele-Leidig has recently uploaded some pieces, I was reminded that he created this wonderful transcription of an improvisation by Sietze de Vries last year. Many thanks to Joachim for this incredible work, which allows us to study the improvisations of a true master as sheet music.

I have selected four variations:
Var. 5: 0:00
Var. 3: 1:52
Var. 6: 3:45
Var. 4: 5:37

The score is available at:
