The birth of the modern structure of Breton bombards

The Kenvreuriezh ar Viniaouerien is a brotherhood of pipers founded in Paris in 1932 by Breton emigrants. Faced with defective instruments, member Dorig Le Voyer started manufacturing them and decided to impose B-flat as the unique key for bombards. This decision durably influenced the musical movement, as did the sidelining of the veuze in favor of these new standards.
