A flash based mixing desk for experimentation with the elements of music. See it in action here: http://www.youtube.com/watch?v=X7FpRcGot4k
This is a flash based resource developed by myself and our web design team at our school.
By manipulating the sliders, students can investigate the effect of changing each of the musical elements in the way that music changes.
This is a zip file so you will need to extract it to the PC or network on which you are working. Then open the html file and enjoy.
