*Sound is a vibration that propagates as an audible mechanical wave of pressure and displacement, through a medium such as air or water.*

I always wondered how pianos work. So I did some reasearch and created [this video](https://youtu.be/gNNkhop45G8). Hope you like it.

__The piano model itself__ is a modified model from [andreschneider's](http://www.blendswap.com/user/andreschneider) [Pianos](http://www.blendswap.com/blends/view/75985) blend published under the CC-BY licence.

- Blend contains 2 scenes. *SingleKey* with one HQ key, and *88Keys* with 88 LQ keys.
- The key skeleton comes with 3 NLA strips: Rapid, Begin, and End. Play the animation to see what they do.
