Somebody to Love rehearsing

Somebody to love is my solo/ensemble song, where my character Scaramouche is wishing to break free and find someone who loves her for her. The ensemble consists of Scaramouche and the teen queens/gaga girls, who prior to this are taunting and mocking her. Practising this with the off cast members, we rehearsed our levels of energy by reading the script and exaggerating our reactions to each other. The teen queens are a version of a snobby group of squeaky girls. We discussed how they should enter whilst i am singing 'Break Free', where they could be catching me singing and sneak in to ridicule me. I contributed my giving ideas about how their formation can be around and above me as I am on the lower stage block. In addition, they could be clicking side to side during the song as if they are proper backing singers. We needed to work o the timing for the last section, where all the voices build up and I belt a high note. This would be helpful to go through with piano accompaniment to compare the timing. I need to work on parts of the song I am finding tricky as I lead the song, therefore the leader of the ensemble. I need to take control and guide my cast members so we can deliver a polished performance.
