The piston is a type of oboe invented by Breton musician, teacher, and luthier Youenn Le Bihan in 1983. The pistoñ is a contemporary development of the hautbois, classical and/or baroque oboe, influenced by the bombard or talabard, the traditional double reed instrument of Brittany. It is typically rooted in the key of D and features post-mounted simple system key-work to expand its range. The tone of the pistoñ stands in a warm and rich middle ground between the trumpet-like tone of the bombard and that of the baroque oboe. The bore is similar to that of a baroque or classical oboe.
