While violin technique literature is extensive, comparable resources for the viola are limited. As a result, advanced violists and educators often rely on violin-based materials, even though the viola presents distinct physical demands related to size, string tension, response, and ergonomics. Most existing viola methods present technique through a single approach and are written as linear method books, making it difficult for players and early-career teachers to quickly identify and address specific technical issues. This project proposes the creation of a first-of-its-kind diagnostic guide for advanced viola technique. Instead of promoting a single technical system, the book will be organized around 77 common technical symptoms experienced by violists. Each entry will describe the problem, identify underlying causes, and present multiple solutions drawn from eight established schools of string pedagogy (including Auer, Flesch, Galamian, Rolland, Delay, Fischer, Primrose, Tuttle).
