Musical instrument family
The clarinet family is a musical instrument family of various sizes and types of clarinets, including the well-known B♭ clarinet, his "brother" A clarinet, the bass clarinet, and the slightly less familiar E♭ and among others.

Clarinets other than the standard B♭ and A clarinets are sometimes known as harmony clarinets. There are many differently-pitched clarinet types, some of which are very rare. They may be grouped into sub-families, but grouping and terminology vary; the list below reflects popular usage and compares it with systems advocated by a few influential authors.
