So while I am waiting for my piano to be finally delivered (any day now!) I have been relentlessly trying to suck in some theory, but I found most explanations on key signatures and their effect on how to play notes from the sheet on the actual keyboard rather confusing or unclear. In the same sense that whole chord thing is a mess! I finally found some resources that seem to make the thing maybe not easier, but definitely more clear and easy to understand, so I'd like to share those :)

A good chords intro which makes sense! https://www.youtube.com/watch?v=cepQVdpZB5U

I know there is no holy grail for all of this, but this definitely helped to clear some things up for myself.

Please dont beat me with a stick!
