I'm excerpting the comments on my role not because I like them, but because I agree with them; starting to beef up my lower register once I was cast wasn't nearly enough time, and I need to learn how to do "commanding stage presence". With that, here's what the judges said:
Dame Carruthers’ role requires a certain robust authority which [I] lacked and she did not make a very formidable Dame, despite her confident stage presence. [Well, I like that bit about the "confident stage presence". ;)] In Act II she picked up energy, and the duet with Sergeant Meryll was a nice romp. [Because I got to dance! :D]
[Carruthers] and [Sgt. Meryll] were both weak in their lower registers, especially for Carruthers in her Act I song, lacking the required range.
Throughout the rehearsal process I felt like the weak link in the principals chain. While I'm sorry to be right about that, I also feel that, if I were to sing the role today, not 6 months later, that weak lower register would have more power & resonance. Ah well; I'll keep plugging away and eventually I'll be ready for the roles I've already done. ;)
