Here is a picture of the concert set-up before our performance this afternoon.
Last year, the PTO raised funds to purchase 12 Wenger Flip Forms to be used as a portable stage and also as risers. I think the students feel more professional and are more focused when they sit on the stage instead of the gym floor. I have a few instruments on rolling carts which remained on the gym floor behind the stage, along with two basses which use chairs to sit.
The black curtain backdrop is actually 4 king size flat sheets sewn together. A parent volunteer created these and sewed button holes in the top. We used individual binder rings to loop them into an industrial steel wire which was installed by our maintenance department. The curtain can easily be pushed over to a corner when not in use. It does collect dust very easily, but I simply take a lint roller to spot clean before any performance.
For this performance, I used safety pins to hang snowflakes as a decoration. I borrowed from the PTO. They have lots of decorations which are used to make our lunchroom festive for the Sweets With Santa event each year.
The projector and screen were installed with money from the renovation. I make a slide for each song and also a slide to introduce the Orff Ensemble and the Choir. If I use audio tracks to accompany the choir, I embed them into the Powerpoint so that they play immediately when the slide is advanced. Since I can't dim the lights, I choose contrasting colors and a large font to make sure the words can be read well. I also test slides in the gym a few days before and make adjustments if needed.
If you also have to perform in a gym, I would love to see how you transform your space into a performance hall. You may follow this link to Facebook to add your pictures. https://www.facebook.com/MusicWithMrsDennis/posts/923423201072823
