This video had to have been from the late 1920s to early 1930s when they started attaching soundtracks to films is series of scenes from Broadway in New York City. The music goes from optimistic fanfare to more calm and serene then an ending cadence. And the sound surely some of it were dubbed the whistle of a policeman, the honk of a horn, or the bells of a streetcar. I wish that we can see similar films or vids of how a city would look in the modern day. It wouldn't matter if it was Chicago, New York or even Los Angeles.
