How do you feel about having someone sing only one or two of the songs from a cycle?

I don’t mind at all. And although my preference would be for you to perform a complete cycle, it would also be fine with me if you created your own grouping from various cycles. This is a bit tricky, however, even for me — as one has to balance many factors (emotions, poetic styles, melodies, harmonies, etc.) to ensure a good dramatic flow.
