Simon Barker sets out the developmental processes he has followed creating an improvisational language for the drumset utilizing Korean rhythm/sticking cells, aesthetic conceptions, improvisatory codes, and developmental procedures. He offers historical overviews of Korean traditional rhythmic forms, analysis of rhythmic structures, an account of his development of a 'Koreanized' approach to the drumset, a methodology for performing p?ansori accompaniment on the drumset, an introduction to Korean extended techniques, and a large collection of drumset studies based on Korean traditional forms. The book includes a CD featuring recordings of developmental exercises, solo drumset improvisations, and ensemble performances, each track representing a subject of discussion within the volume.
