Automated piano. Need help finding music!
 

Hi, i'm a last-year student in a highschool in Belgium, and i'm going into the last few weeks of my end-term project. To finish it, I need to automate a piano using a PLC (Insert boring technical stuff here).

Now, the only piano keys (due to complications) i can use are (in order):

C,D,E,F,G,A,C,D,F

. That's it.

If anybody could link me to sheet music that only uses these keys, that would be awesome. It's not easy finding music this way, but i don't have a choice anymore. Thanks for helping out!

PS: Music that is well-known would be amazing. It would be awesome if people recognized the songs!
