Actus Model
A model in development, based on proportional studies from the opening of Bach’s Actus Tragicus, BWV 106.
Actus Tragicus — BWV 106
The Actus Model is a development study for a future instrument model at Badiarov Violins.
The study began in April 2025 with the opening bars of Bach’s Actus Tragicus, BWV 106. The musical relationships in those bars are being tested as a source for proportion, balance, and form.
The music gives useful context for the character being studied before the instrument itself is made.
The next stage is more specific: adapting those proportional relationships to the way a particular musician intonates and physically experiences the theme.
The model is not yet part of the regular collection.

Development studies are part of the atelier’s research process. They may occasionally result in individual instruments, but they are not regular models until the design has been tested, refined, and accepted into the collection.
