If you rent the hall, you likely have a lot of flexibility in choosing a shooting position. In this case, my location choice was the front row.
Being in the front row opens up new possibilities for wide angle compositions that incorporate the stage without having audience in the frame. I'm always a fan of the leading lines provided by wood stage flooring and the sound panels in the ceiling provide a balance to the bright floor. With a manual exposure dialed in (the lighting was constant), I simply framed and waited for the preferred bow arm position to press the shutter release.
