Double reed instrument, the bass of the woodwind family.

Fagotto in Italian, and something similar in most other languages I guess because it looks like a stick (or bundle of sticks?), though the English word probably comes from "basso."

It's the grandfather in Peter and the Wolf. This should link to the sound -
