My latest YouTube video covers the topic of using paradiddles as grooves between the snare and bass so instead of playing R L R R L R L L you play B L B B L B L L and so on. It’s a great way to develop your ghost notes including balancing the ghosted and accented notes in different ways. It will also improve bass drum coordination and can be used to increase bass drum speed and endurance if you’re inclined so to do.
