Mastery for Strings presents a unique, efficient methodology for developing high levels of proficiency in string players in both classroom and private studio settings. Cornerstones of the Mastery for Strings approach are: A curriculum design for large heterogeneous string classes; Technical skills organized in small, sequential steps; "How-to" pages with clear goals, explicit instructions, and recognizable evaluation criteria for each technical skill; A plan for developing problem-solving strategies and self-evaluation skills; Music theory (fingerboard geography) taught without reference to the piano keyboard.
