I am running late, but finally managed to release a transcription of the first movement of C.P.E. Bach's Magnificat. I created it while I was the Artistic Director for the International Choir & Orchestra of Ho Chi Minh City, at a time when there was no free score available. We were able to find some hand written parts and used those to create the score and parts that I have published today.
While it is not an edition of the complete work, this movement is substantial enough on its own to stand as a concert piece. It is a bit difficult, especially for the violins, but well worth the effort. I hope you will enjoy it.
