Inspired by this article about the endless supply of adaptations of Bach’s music, I started looking for some myself and found Egon Petri’s transcription of “Sheep May Safely Graze” from Bach’s Cantata 208 (free score here.) Here it is performed by Yeol Eum Son, silver medalist in the 2009 Van Cliburn Competiton. Enjoy!

Looking for sheet music of Petri’s other Bach arrangements: Bach Menuets BWV 841 and 843, recorded together in 1935, and also recorded by Andrew Rangell (all 3, including Sheep My Safely Graze Cantata 208) . Does the music exist?
