Stuck: Need upper right piece for "Ode of Joy"

Hi, I just need this piece to end the last song "Ode to Joy" (all others are solved). All rooms have the HO counter to 0, except the basement. There it says I am missing one, but no matter how long I wait nothing glitters.
I also checked LizzieK's pics and she says there were 10 outlines in the basement and I have located the 10 she shows. Still the counter says one is missing in that room. I'm stuck here since yesterday.
Can anyone help?
Thanks

The same thing happened to me. The lower edge doesn't show is some games in windowed unless your resolution is higher. The new Veronica Rivers game is the same way.

Many thanks LizzieK. In the basement I was missing the code "on the strange instrument on the left". I could see the sparkle, but I had failed to click on the top of the violin in the box at the front of the basement view. Were it not for your photo I would have continue to click on the strange instrument forever in vain. Now I'm off to finish the Ode to Joy. Great game!!! Hope there will be another.
