The flam accent is included because of its unique hand motion, which involves a downstroke with a quick transition into a low triple beat. Mastering the flam accent will open doors that allow you to play many other rudiments, as well as numerous patterns on the drumset that may seem unrelated. I can’t remember the last time I played flam accents on the kit, but because I can do so, my hands have the ability to execute many other useful musical ideas.
