Ostinato is defined as a phrase that is clearly defined (both pitches and rhythm) that consistently repeats throughout work or passage. In other words, it can also be defined as notes that consist of repeated patterns.
Herrmann uses ostinato at the high points of music in the films where notes are consistently repeated with high pitches at a particular time. The ostinato technique is important as it captures the full attention of the viewer who anticipates what is going to happen next. It creates a sense of suspense/tension or anxiety that excites the viewers (Beek).
