No, hard rock will not do that, the best way is to find a comfortable ar which is not too fast nor to slow. Play maps which you have good accuracy already and try to acc them better, its on you what way you find comfortable, You can listen to beat to tap accurately, you can focus on approach circle to find the time when you need to tap or you can do mix of both.
Some advice:
Read note individually: In my opinion everyone should learn this skill because not only it improve your consistency, it also improve your accuracy, I went from 94% average to almost 99% average. And to improve reading is by playing low star maps which will give passions which you need to read note individually.
Diversity: Play a lot of different type of maps, Two most important is of course stream and jump but you should also focus on tech maps and finger control maps. As the name suggest "finger control" means to have a good control on your finger which will improve your accuracy.
Tech maps: Tech maps itself have different variety. Some are heavily based on aim like fast slider or some are based on finger control like sputnik. Tech maps is most fun way to improve any skill you want to improve, of course if you are someone who like to challenge themselves.
Playing in your comfortzone: Play in your comfortzone and play easy map so you can focus on accuracy
