The plodding hooves of farmhorse differ from a cavalry company riding at full speed. The vibrating tone of a gong may offer a slowly decaying accent, while a sudden sneeze provides a brief one. In a gangster film, a machine gun's fire crates a regular rapid beat, while the sporadic reports of pistols may come at irregular intervals. Any consideration of rhythmic uses of sound is complicated by the fact that movements in the images themselves have a rhythm as well, distinguished by the same principles of beat, speed, and accent. In addition, the editing has a rhythm.
Short shots helps crate a rapid tempo, whereas shots held longer tend to slow down the rhythm.
In most cases the rhythms of editing, of movement within the image, any of sound all cooperate. The most common tendency is for the filmmaker to match visual and sonic rhythms to each other. Mickey Mouse and the other Disney characters often move in exact synchronization with music, even when they are not dancing. By fidelity David Bordwell and Kristin Thompson do not mean quality of recording. Fidelity refers to the extent to which the sound is faithful to the source as we, the audience conceive it.
