Rhythm, for Orff as it was for Stravinsky, is often the primary musical element. Overall, it sounds rhythmically straightforward and simple, but the metre will change freely from one measure to the next. While the rhythmic arc in a section is taken as a whole, a measure of five may be followed by one of seven, to one of four, and so on, often with caesura marked between them. These constant rhythmic changes combined with the caesura create a very "conversational" feel – so much so that the rhythmic complexities of the piece are often overlooked.
