... if you want it to be performed, or be particularly useful, would you please write a short (under 40 min.) opera for 2 sops and a mezzo? With piano and whatever additional instruments.
I know you may be looking for creative inspiration through plot, but what needs doing is real dramatic writing for female voices aged 20-24 for minimal ensemble.
I believe that 'opera' means three-dimensional, acted-out music. And training female singers have got the short end of the stick all these years.
