Where do you focus on the gameplay screen?

Do you focus on the arrow bar where your keys actually strike for hits/misses or do you watch the field of arrows as they move towards said bar?

I typically have been staring at just the bar and striking keys as they cross that plane but as I've progressed to more difficult songs it sort of makes the field of arrows blur as it gets more dense.

I hope I haven't developed a bad habit because now I'm forcing myself to stare into the field, otherwise it just becomes a bunch of blurred jargon if I focus on the keystrike bar.

Sorry for the lack of clarity. Hopefully this makes sense and I can get some feedback on what exactly everyone else does.
