Set up a photo for the cover that relates to a primary topic of interest from the issue. For example, if the issue covers various versions of "Swan Lake," have an individual dressed for one of the production's primary roles pose for the cover. Use an actual dancer, instead of a hired model, to get the most authentic result.
Have a dance-related illustration created for the cover. Dance and art often go hand in hand, as artists love conveying a dancer's movement in their work. An artist can draw a picture of a dancer, an onstage production, or a dancer's clothing. Have them use colors that are used throughout the magazine, and in the magazine's title, so the cover will seamlessly tie the issue together.
Convey dance in its most natural state, by photographing a dance class in session. Visit a class, and ask the instructor for permission to take some candid pictures throughout it. This may be a dance class for kids, or one that's intermediate or advanced. Select the level to photograph based on a topic of discussion in the issue. This will make for a very relatable cover for any dance enthusiast. Be sure to get signed releases from your "models."
For an issue that focuses on a variety of key topics, create a collage for the cover. The collage can feature photographs and drawings. Create them yourself, or have dance classes and dancers send them in to be featured. If possible, you can place an ad for this in a previous issue or send the offer to local dance groups. This will be a fun cover to create, and your readers will feel more connected to the publication.
