In February 2022, I went to New Orleans to record a song for the AMC series "Interview With a Vampire." The film set was in the French Quarter, in the courtyard of a historic home formerly belonging to General Beauregard. I was not allowed to take photos, so here is an image from the internet:
I spent many hours on the set and it was made clear to me that I had to be quiet. The production people would call out "Quiet on the set!" every time they were about to film a scene, which was pretty often. I did not want to find out what happened if you were noisy on the set.
At one point, I heard faint drums and brass in the distance. Before I knew it, a small second line was marching down the street, right in front of the house. Needless to say, there was loudness on the set. But the filming did not stop for a moment. They just carried on as if everything was normal.
So why were they were so insistent on having quiet on the set? If a brass band doesn't disrupt the filming, does one really need to be quiet on the set? And that reminds me, do you really need to turn off your cell phone on an airplane? I'm afraid I cannot answer these questions, I'm just a piano player.
What I can do is pianistically recreate the experience of a marching band passing by. In fact, this was a common thing back in the early 1900s. There was a popular kind of march called a "patrol" that would start out quiet as a whisper, grow to a fortissimo by the middle of the piece, and as it neared the end, the music would return to a whisper and fade away. The point was to recreate the experience of a marching band passing by.
Here is my pianistic re-creation of a New Orleans second line. A patrol, if you will. I present to you the New Orleans classic - "South Rampart Street Parade." Quiet on the set!
