The first 3 grades as a drum kit student are mainly to establish technique, reading and knowledge of genres and their place in music history.  The next three are more about establishing a more deep level of proficiency whilst the last two really establish the student as one that is ready for a career in the music business as a session drummer, a teacher, or a performer in a function band or an original band.  www.westlondon-drumtutor.com  From west london drum tutor, drum kit tuition in Harrow, Greater London, UK
