Error: No module named sound device

I am very new to this and have little to no programming or rasberry pi knowledge. I spent a long while trying to install on the microSD card but finally resorted to copying and pasting the commands from Github into the Terminal. It seemed to be working but I got this error on the final step:
File "samplerbox.py", line 35, in <module>
import sounddevice
ImportError: No module named sounddevice
I hope someone can help and apologies if this is a stupid question, I'm a little out of my depth here.

Hi Person, you starting point should be one of the available images and not just the sources. Otherwise I'm afraid you'll run in quite some more issues and get even more out of depth.
