During his life, Hermann Meier wrote a lot and jotted down his thoughts – his written archives include letters, diaries, workbooks and notes about what he was reading, etc.
His extensive notes about his compositions were written in Stolze-Schrey shorthand.

From 1955 onwards, Meier created graphic composition plans that he then “set to music” in a second step in his working process. These process diagrams became more colourful and multi-layered in the 1960s, and are often reminiscent of Concrete art. In the 1970s, they then formed the basis for Meier’s electronic compositions.
With one exception, Meier wrote his instrumental works in conventional music notation.
