Audio mode on, in the video a road that plays, but only at the right speed

In the video posted on the Twitter profile @CrazyVidKid it is possible to listen to the performance of one Musical Road. A musical road is a road, or section of road, that when driven on causes a tactile vibration and an audible rumble that can be felt through the wheels and bodywork of the vehicle. This rumble is heard inside the car and in the surrounding area, in the form of a musical melody. Music streets currently exist in Denmark, Hungary, Japan, South Korea, the United States, China, Iran, Taiwan and Indonesia. Each note is produced by varying the spacing of the strips and the frequency varies according to the speed, so to have the best aural experience it is therefore advisable to travel the stretch of road at the right speed.
