That's very beautiful, wow, thank you for posting this.
For a lark I once played organ pipes of an organ that was being decommissioned. It is absolutely incredible how much air that requires, a 8' pipe I could just about get to resonate, and once they resonate it becomes a lot easier because you have some backpressure but that initial rush to get the reed to move at all is quite literally breathtaking.
To answer the 'dead' comment below: yes, I actually did. Nicely cleaned it and I'm aware what organ metal is made of (it is not the safest substance in the world). Would recommend.
