Which instrument is NOT part of the viol family?

The viol family includes instruments that are characterized by their shape, string arrangement, and playing style, typically played with a bow and having a fingerboard without significant frets. The instruments within this family include the viola, violone, and others that share similar construction and playing techniques.

The violoboe is not recognized as an established instrument within the well-known viol family. While the name may suggest a connection, it does not represent a legitimate instrument like the viola, which is a standard member of the viol family, or the violone, which is a larger bass string instrument related to the viola da gamba.

Therefore, the correct choice identifying an instrument that does not belong to the viol family is the violoboe, as it is not a recognized or traditional instrument typically associated with this lineage of string instruments.
