Armor Games

I'm up to the piano and know I need to play the same tune from the recording, but whenever I try to nothing happens and now I'm stuck.  Any help would be appreciated.

I reccomend readsing the walkthrouhg if you're stuck... I actually thought the lines of the recorder were the music staff, but then all of them didn't match up, and you can click anywhere on the keyboard and not be entirely  sure what note you are playing so... dat messed me up after the pi part.

The recording is a half step (semitone) flat.

The notes are C D D B A.

For those of you who don't have an actual piano to figure out the keys on, use a virtual piano like this one:

I hope you know by the authors name it says " Game walkthrough".

Thanks for the help!  I think I was just having an air head moment.

What number do you put in the phone in the end
