I hear a drum beat. I get closer, then I start to hear the guitar, flute, or bagpipes.
I always here the bagpipes first before I hear the drums.
You do not.
Not unless you're Scottish. Scottish ppl can nae hear the drums first, for they are always listening to the wee bagpipes in their soul.
Why don't you concentrate on the speed issue?
I am. I just gave you a good example of a situation where things of different speeds nonetheless intersect. It's not even the only one. When the snail, the cat, the dog, the skateboarder are starting out, they are all of different speeds but we can say that they are also in proximity. It lasts more moments the you think for a snail to move away from a car, as we do not care about perfect alignment but that the snail is within the proximity of the car. If the snail moves past the car (it has trouble starting for example), the snail wins even if the car's total speed is greater.
Proximity effect is why we can hear sounds of different speed as music. They register at the speed of sound, and it takes awhile for them to disperse. Less like a car and snail, and more like a cat and dog.
Cats are sprinters, dogs are endurance runners. Both start out as roughly 30 mph. But wilder breeds of cats can reach up to 70 mph. So that's it, cat wins? You've obviously not read the tortoise and the hare. The dog may be able to only run 30 mph but they can run for longer and can catch up, and possibly pass a wild cat like a cheetah. Especially if that dog is also wild (wolves have impressive endurance).
The same is true of sound waves. Slower frequencies carry for longer. Or in layman's terms, slow and steady wins the race.
I dunno about bagpipes as they do have a kinda drone (I don't happen to live where bagpipes are played), but western music, even when the guitar is loud, the drum still carries better. Different speeds don't necessarily mean that the music breaks apart instantly.
