An expedition of archaeologists has found these strange marks on a titanium plaque in a devastated part of the Antarctica on 1. April 2007.
After a short analysis, they discovered that the plaque is more than a million years old and definitely of extraterrestrial origin.
The plaque was immediately passed to NASA scientists.
Two months of continuous research brought no further results.
But most of the scientists agree that this must be some kind of music notation...
Maybe an alien race tried to contact us over a million years ago.
The NASA now has decided to make a public competition to get the information of this music piece.
Musicians of the whole planet are asked to bring a solution for this problem.
Maybe the future of our planet will depend on this.
Please translate this sketch into music.
