The author Wolfgang Fiwek observes the self-taught violin maker Klaus Andrees and details his method for the reader. Step by step, a high-quality instrument is created. Andrees has developed a technique over many years of experimentation, which he gladly shares without the secrecy often found in this field. His instruments are now played by top musicians. This method enables anyone with basic knowledge and a standard workshop setup (along with some specialized tools for instrument making) to build a violin or viola of good quality.
