The Piano Falling scene

After much work, and using many new effects shown below I finally created my piano falling down the stairs scene.
This scene lasts for 15 seconds, and involves a combination of jazz music overlaid on itself so that would sound more like a piano falling.
The scene uses one camera which rotates to give the best view of the piano throughout.
The textures are the combination of the architectural ones used in the piano tutorial, and basic images overlaid (wallpaper for example).
The final animation is shown below:
