The participation works as follows:

1. You choose and download the sheet music and the corresponding sing-along or play-along files using the links provided in the instructions PDF, that you can download here or in the "NEWS & more" page:

2.You practice your part along to the playback recording.

3. When you are familiar with your part, then you perform it to the playback and shoot a video of your performance. Please use headphones, so we hear only your playing!
Don't forget to clap loudly at the beginning of your video recording in sync with the children, along to the countdown!

4. In addition to your performance video I ask you to shoot two more videos:  
a 30 second video of a lovely place where nature is still intact, and another video of a place where nature is suffering under a heavy human footprint. Slow camera pans work here best!

5. Finally, use the link provided in the instrucions PDF to open the upload form, then fill out the form and upload your videos.

Here you find a diagram explaining the procedure:

I will produce a great concert video using your performance videos, which will then be released for the public all over the world!

I divided this 24-minute oratorio into four separate sections, each with its own sing-along or play-along files, so you don't necessarily have to join in on all of the parts. But of course you can, if you want!
For amateurs the fourth part works best, since it is not difficult to be sung and can be managed  even without knowing how to read the sheet music.
