I have the four musical notes and know the order to place them when the funeral march plays: However, the red light does not turn green. I went back to a save and replayed the composers rooms to gather the notes again, but that didn't work. This second time I saved just before I pulled the cord to start the music and tried again, but still no luck. I am playing on a flat screen iMac in OS 10.10. I have checked the Lisssn website and the walkthrough. If anyone knows of a cheat to get past this, please let me know. Otherwise, I won't be able to finish the game.

I am sorry that you have run into this problem. I found a thread about this organ puzzle here on Steam. It includes comments from the developer and I hope it will be of some help to you. The walkthrough mentioned is in German, but you could run it through Google translate. Let me know if you want to look at the walkthrough but don't know how to run it through a translator.

Thank you, Marian. The walkthrough is also in English, and I have looked at it. I'll check out Steam, although I think they only have the Win version.

Edit: They're discussing a different puzzle, but thanks anyway.

Oh, rats. My mistake for assuming there was only one organ puzzle.

Maybe you can leave a message for the developer on that forum? Or maybe there is some other way he can be contacted?

Good news! I quit the game again and when I placed the notes, I got the green light. Now I can finish the game!

Edit: I finished the game tonight. With its first person exploration, many fun puzzles, and lovely music, it was a treat for me to play.

That is great news, LadyK. I'm glad to hear you enjoyed the game.
