Howard's bassoon is a musical instrument that is only seen in the episode "New Fish in Town" and belongs to Howard. The bassoon is a woodwind instrument that is in the double reed family, and has its music usually written in bass clef, but occasionally can reach the treble clef as well. It is most commonly found in orchestras, ensembles, and concert bands.
The instrument is a blue metallic bassoon with a long row of keys and has a curved and silver bocal coming out from the body of the instrument.
When Squidward is having a conversation with Howard, Howard mentions that he plays the bassoon. He and Squidward head inside of his trailer where they perform their own instruments together with Squidward using his clarinet.
