Documentation to make a rhythm game (request)

Hello everyone. I wanted to create a rhythm game. I never made games before, so I thought it's be better to follow a tutorial to learn how to make a rhythm game (this link). But, this tutorial has mistakes, and I had to correct some things (I never learnt c#, I know it can be stupid to create a game without knowing anything in programmation, but it's a good exercise ). Also, after checking internet, I noticed that the code I have is absolutely not the same I saw.

So my request is : do you have good documentation to make a rhythm game?
