The Most Underrated Fundamental in Learning Music (IMO)

Perhaps the title is bold. Oh well yolo. Sorry I look pretty rough; it was like 4am. :D
I haven't made a video this educational in a while. Do you guys like when I post long tutorials like this? The last time I uploaded a jazz one was for the "How To Play The Mario Kart Lick," which was quite some time ago. Now that my audience much bigger now, I'm not sure what everyone prefers. My short meme-y vids? My long tutorial vids? More original music? More classical sax? Help me out here plz lol
