While rehearsing Copland's Appalachian Spring with The Knights this afternoon, the strings were trying to find the right sound for a hymnlike passage in the final pages. Eric Jacobsen suggested they hum it. What a great sound these twenty young virtuoso string players made singing together. Hushed, focused, gentle, earnest; it was perfect. I know the recording tomorrow will capture those characteristics, but I'm sure glad I heard it sung.
(By the way, Zéphyros used the technique for a passage in our Gounod recording . . . )
