Don't get me wrong, it's great that you are creating these tutorials, but I think you should try to make them look more like tutorials, and not just a screen capture videos.
Say, before doing something in the editor, add a static frame for a few seconds explaining what are you going to do.
For example: "And now I will add an instance variable MusicalNote to piano keys and assign each key its own musical note".
This will make a huge difference!
Also, if your tutorial is in several parts, add a description to each part:
Part 1 - In this part I'm creating graphics and visuals
Part 2 - In this part I'm adding a title screen
And since you are doing this for the viewers who are mostly beginners, try not to do everything in a hurry and record the whole project in one go. Your don't make pauses, mouse movement often look chaotic, windows are opening-closing too fast etc. I almost got a headache after a couple of minutes watching your videos.
