This animation makes great use of sound and has a very simple theme, easily achieved in the short amount of time we had, simply explaining an area of music theory.
This speed animation approach I use for conferences and mixed training days produces some great results from participants who focus on subject/topic areas that are familiar to them. These teachers produced a resource that they knew would have relevance to an area of their curriculum and subject. Maybe in the past they had wondered how they could teach this nugget of theory in a fun engaging way. That quickly got the important points across to their students.
