Music Room Escape

[Lido]

I playes the four musics and heard the creaky sound but still can't get out. Where do I have to click please?

Wow, that's really the power of posting, I just tried again and it worked.
So if you're stuck wait a bit and retry

Clever! Would have liked some sound though especially when clicking the piano

"I survived? You contrarily opened the door with the word by thinking barely."

Now while I have been accused of thinking barely in the past, I'm assuming that the important thing is that I escaped, hm?

There are three spots on the floor that you need to push, the left one is to get the diary and after that you click the tapes to get the key, the middle is the creaky spot you click at the end, and the right (next to the stand) is the spot you push to get the order of numbers.
