The Promenade Concert, referred to as "Proms", means that the audience can stand and enjoy the concert in the concert hall, and is allowed to move around at will, just like taking a walk. At the Proms, you can see a scene that is completely different from traditional classical concerts: many people are wearing casual clothes and listening to the concert, and some are drinking and eating. At the climax of the performance, the audience I can't help but sing along loudly, and even shout and cheer like I'm watching a football game. The world's largest and most democratic music festival.
