Our Music Director Holly Mathieson has the answer to this one!
Whichever school of technique you learn, its aim is to teach you how to be hyper-aware of every movement you make and the audible effect it has. We want every gesture to be considered and intentional, and to lose unconscious habits. So start with the most neutral gesture you can do. Once you feel comfortable with that, you can start to add musical “instructions” for the player with your gestures, based on what you see in the score. Crucially, it’s not about showing how we feel, but using technique to help the musicians play the work as well as possible.
