Book excerpt: Volume II is aimed at two distinct categories of readers: 1) Intermediate players who are ready for a wider range of rhythms to study and use in live playing situations; and 2) Experienced congueros who have digested Volume I and now seek to understand the roots of the modern Cuban conga style. Having assimilated the material in Volume I, the student should be able to play basic Son Montuno, Salsa, Chachacha, and Bolero. Volume II moves on to Guaguanco, Iyesa, 6/8, Changui, Afro, Mozambique, Pilon, Songo, Merengue, Bomba, Cumbia and other rhythms that a professional conguero will be expected to know. Each rhythm is accompanied by an article reflecting on its history and role in the "big picture" of Latin music and offering listening recommendations. Like Volume I, it uses the Step by Step online video Method. A special 8-page appendix explains the often infuriatingly complex subject of "clave" with an unprecedented level of clarity and insight. Includes access to online video.
