Food for thought:
When you look at songs to sing ... remember the hardest moments could be in the ‘stillness’ the character needs to live through! It is also the hardest to be that still and vulnerable and think ‘I’m not doing anything’.
There is more power in emotion that is has no movement.
To get to that vulnerability you can use movement as an exercise! You also have to have worked on yourself and what you can bring to the vulnerability to then create the character. When you achieve this the next step is figuring out the 'why' is the character still?
The new video Of Shoshana Bean and Cynthia Erivo is an example and done by two amazing singer/actresses.
Another example is Jessie Mueller singing 'She used to be mine'
