bassoon
The bassoon is a woodwind instrument in the double reed family that typically plays music written in the bass and tenor clefs, and occasionally the treble. The bassoon is a non-transposing instrument known for its distinctive tone color, wide range, variety of character and agility. Listeners often compare its warm, dark, reedy timbre to that of a male baritone voice. Someone who plays the bassoon is called a bassoonist.
Fun fact: It's also called a Fagott.
