Music can rarely be felt

What are you trying to do that you can't?

We currently vibrate Music output if supported by the vibration API, but it only really works for Android mobile devices. That greatly limits the devices on which one can feel music.

What is your idea?

The gamepad API is widely supported and more expressive. Let's design a mapping from music to gamepad vibration.

Pulling in ideas from #1309, which raised the same need. Two things from it that belong here too:

• Gamepad rumble is the near-term channel. If the web gains richer haptics, or a custom haptic device turns out to be worth supporting, that work lives in this issue rather than a new one.
• The open design question is what good music haptics even are. Co-design with deaf and hard-of-hearing folks before settling on a mapping.
