Gillian, I enjoyed the video. But could you make a video about how to decide what to do a course about. I don't run a teaching channel. My channel is an entertainment channel about hip-hop music production. I'm really not sure what to do a course on.
You could do a course on programming drums, mixing, recording vocals, using samples. Those come to mind. Or you could do a masterclass sort of course that covers all of the essential steps to creating a song or beat. How to make money as a hip hop producer would be good too. People are more likely to buy something if they can clearly see that it's an investment.
