Great Music Moments in Film:

The finale of Once Upon a Time in the West consists of the grandiose showdown between the nameless “Harmonica” (Charles Bronson) and his nemesis, the sadistic Frank (Henry Fonda). The entire film (all 175 minutes of it) had been leading up to this moment. The two character’s paths had taken drastic twists and turns, together and separately, so when they finally go head to head it’s a landmark event. The element that makes this situation so much more larger-than-life is the inclusion of the flawless Ennio Morricone track “Man with a Harmonica”. It immediately sets the tone for the scene. Even if you've never seen the movie, when you watch the final duel you can tell how important it is. It’s one of my favorite scenes in the history of cinema, hands down.
