Danielle Woerner wrote an interesting post about memorization as a singer (among other things) that's too long to quote really. I'm wondering about language/textual problems, that are unique to singers (vs instrumentalists). It seems to me that singing a song in say, Czech [assuming you don't know Czech] would be more difficult without the music even if you had every note memorized. Is this a factor when singers decide whether to use the music in performance? Bob K.
