I have not seen the video and don't intend to, because, quite simply:
- Nine-year-olds shouldn't be singing Puccini (or any other opera, really).
- Nine-year-olds are not competent to teach themselves to sing opera by watching YouTube.
- I'm not adding to the excessive attention this child is getting.
Anne Midgette speaks for me. I mean, I think the word purist should be banished from these discussions, because what is meant is "people who know something about opera and singing." But whatever; I'm especially pleased that Anne mentions that the aria is a comic aria. This is obvious in context (and Gianni Schicchi is the funniest hour of opera ever composed, at least in the production SF Opera used in 2009) but most sopranos recording for recital discs don't put it across very well.
