Depending on what her long term goals are for playing drums.........like so many other instruments.......the fundamentals are there to create a foundation that will help her in every possible drumming situation. In another view.......the fundamentals also come with a learning of universal terminology used by drummers and other musicians the world over. Sort of like the guitar player or piano player (or etc etc) who never thought learning what a song key was all about was important............who later realized he had no idea what to do when a singer asked to do it in a different key. Obviously a key does not affect the drums.......(mostly).......but the point is that many professional musicians understand drum terminology as well and use it.
As a separate question of a similar nature........does she consider learning time signatures important? Not saying she does or doesn't.....just wondering.
