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. First and foremost, remember to be organized and prioritize.
There are a lot of processes you will want to be familiar with and keep an eye on:
Top Priority:
Other Administrative:
Other Procedural:
It is imperative that you select your Producer, SM, and TD carefully. They will set the attitude for the show. While it is difficult to be Chair and Producer simultaneously, it is worth considering. Technically, the term show is not your responsibility once a producer is selected, but it is always good to keep an eye on it. You should be using your knowledge of ensemble history and your awareness as an officer to predict what could go wrong and make sure the right people have it on their radar. As the chair, you theoretically have access to all the ensemble's information. The producer and/or SM might not. You should make sure that communication is open, that people have the resources they need to do their job, and that the ensemble as a whole is as coordinated as possible.
Organization is key. You probably already have your own way of keeping organized, but I recommend keeping a list of everything that needs to get done in the ensemble (at present) and highlighting those that you need to take action on. Typically, there will be three to five categories of things and three to five tasks in each category. You will probably have three to five things you are directly responsible for at any given time, though if you are spending more than four or five hours a week on Chair responsibilities then you might be doing too much. You can use the list above for inspiration. While some projects may sound fun, they can be difficult in practice. Keep an eye out for these. It is your prerogative to say "No." Make sure people in charge of various things keep you up to date. Check in with them frequently. If things are out of control, decrease their size and scope.
When people are not doing their jobs, you need to think carefully about your response. Sometimes, a simple email will do the trick and get the person back on track. That said, if the tone needs to get harsh then it is best to do it outside email. There is really no substitute for talking to someone in person. Consider a person in the context of all their commitments to the ensemble. If they forgot their term job but were diligent in their production position, you might want to let them go depending on the circumstances. If you do need to take action to a person, try to meet with them in person and explain very clearly what happened and understand why it happened and what can be fixed in the future.
