Rockschool grade 6 introduces the drummer to the professional aspects of being a drummer.  This is where the intermediate drummer becomes an all rounded drummer with elements of creativity. At this stage the drummer learns upper level rudiments, and applies them in a range of contemporary styles (jazz, reggae, rock, blues, Latin...) Grade 6 extends knowledge and application of rudiments, technical exercises, two tests (reading, theory, ear tests, improvisation...).  From West London Drum Tutor, drum tuition in Harrow  http://paltip.com/westlondonenglish/!501b
