We thought a lot about the help in smartChord. The handling of the app is described in the help, tips and the FAQ. And there is our YouTube channel: https://www.youtube.com/c/smartChord. nnThe big open issue is the musical theory. But this is such a wide field with so much themes and topics. We skipped it as there are already so much good web sites where the musical theory is excellently explained. nnThe best advice would be to search the web for the topic you are interested in and use smartChord as a tool to support you.nnThere are a few tutorials about smartChord. It’s the best to search for smartChord on YouTube.
