Another nice music powerpoint slide - this one on African drumming and music which includes some rhythm games. This particular teacher on TES has some very nice music resources and is worth following. What I do when I find someone that I like is to click the "follow" button and then you get notified when they upload new lessons.
When I taught digital film, I had them create a silent movie and then add sound effects and a musical score. Each student used the same film but edited it differently. It was shocking to them how much difference a good soundtrack made. In this powerpoint, you can take students through great composers for film.
