The prime time for me to watch a YouTube tutorial videos is first thing in the morning. For some reason, the information just sticks better. I follow it up with 30 minutes on the drum kit or piano putting the new information into my hands.
Later in the day I will score all or parts of the tutorial to paper. I find that the visualization/transcription process helpful. Then I teach the content to the appropriate students. This further integrates the lesson into my own hands.
If I can help, call me.
