This whole extract is one song called Ecstasy of Gold by Ennio Morricone from the film The Good The Bad And The Ugly. This is one of the most epic films ever made and the soundtrack really expresses this. As the music builds the character we see, Tuco played by Eli Wallach, races to find a grave with the gold inside it. The long it takes for him to find the grave the more the music builds and as he finds the centre of the cemetery the music slows down as he slows down. Towards the end as he continues to gain speed so does the music and the camera movement until finally the music stops suddenly and we see the grave.
