Can anyone explain the music puzzle in chapter 2?

I simply don't get it. I looked up the solution and finished the chapter, but I don't get it. Thanks!

There's a very helpful, spoiler-lite guide by eXntrc. One small clue that helped me is that the "0,5" notation can be translated to 0.5 (as in half of 1), which is the value of the eighth notes.

I think this is something lost in translation, as the uses of commas and periods in numbers are switched depending on the language.

[julia_maluca]

Yeah, but how do I deduct then that I have to double each value? Even if I take the eights as 0,5, why should I then go 1, 2, 4 instead of 1, 2, 3 or 1, 1,5, 2? It just doesn't make sense.

It's not a real pyramid, it's just a hint, all rows have the same sum
8*0,5 = 4
4*x = 4 | x=1
2*x = 4 | x=2
1*x = 4 | x=4
