Overview: From the moment our hearts start beating, rhythm is integral to us all. From walking to dancing, from clicking our fingers to tapping our toes, we are all programmed to respond to rhythm. In this film Howard looks at the common rhythmic patterns that have been used by musicians from all cultures, from Brahms to rappers, from the founders of Cuban son to Philip Glass, from Stevie Wonder to Fats Waller. Why do some rhythms make us want to dance, while others make us feel tranquil? How does rhythm 'work' when there is no obvious pulse, as in much classical music? What links African drumming to J S Bach? Why do virtually all popular singers sing ahead of the beat?
