In what ways can music be used in theatre

The performers may dance to a song, performers could sing, and when something bad is about to happen, you can play scary sound track. Also, when something good is about to happen, or is happening, bubbly and/or cheerful music may be played. I hope I helped :)

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.
