This chapter is fairly easy to pass through, until the end where you have to play a set of drums through a series of notes that the wall keeps playing for you that you have to repeat. I'm always bad at audio puzzles like this, so in order to solve it I had to try every possibility on each round, so I had to write them down each sequence. I don't know if the game randomizes this part of the game, but here was my solution (1 = drum on the left, 2 = middle drum, 3 = drum on the right) by rounds of sequences per line:
2, 3, 1
1, 2, 1
3, 3, 1, 2
1, 3, 3, 2, 2, 2
That should complete the end of this chapter and pop your achieve!
Good luck! I hope your sequence is the same as mine.
