Courtesy of 8-Bit Music Theory. I love his channel and watch whatever video is posted. But in this case, this vid is great for anyone who wants to write their own drum parts. Granted that the vid heavily implies that you can read sheet music but there's still some gold to mine from. In my case, when I started writing music and charting everything, I forced myself to learn how to read, write and transcribe drum notations. It took a ton of patience, practice and criticism from actual drummers, but I'm glad I went that route since it helped me in the long run.
