From the beginning until 0:14 is the introduction, which sets the tone with continuous repeated strings. At 0:14, the melody is presented through the strings, with brass keeping time. As the melody progresses, John Williams often uses high percussion and flute to add extra decoration. Whether it's the brass, winds, or strings with the melody, there is always a group of instruments keeping the tempo with repeated eighth notes. At 2:56, Williams changes things with ascending trumpet runs that lead into the conclusion.
