In general, the chair is responsible for running meetings and keeping an eye on everything happening in the ensemble. It is good to either be familiar with most ensemble processes or know someone who is. Making sure everyone is doing their job can be tricky at times. Ultimately, you will develop your own style. There is also some advice on this page.
There are a lot of processes you will want to be familiar with and keep an eye on:
At the beginning of each semester, choose a time for weekly officer meetings.
Elaborate. Carefully Consider Assigning Term Jobs. Ensemble Philosophy.
Be pragmatic. Invite non-officers (events coordinator, show producer, class coordinator, etc.)
Keep the group updated.
It is imperative that you select your Producer and SM carefully: they will set the attitude for the show. While it is difficult to be Chair and Producer simultaneously, it is worth considering.
Keeping a list of running projects is important. Some projects may sound fun, but will be difficult to in practice. Keep an eye out for these. Make sure people understand how much work they are getting themselves into.
Make sure people in charge of projects keep you up to date. Check in with them frequently. If things seem to be out of control, decrease the size and scope of the project.
