The family clarinet family is a musical instrument family including the well-known B♭ clarinet, the slightly less familiar E♭, A, and bass clarinets, and other clarinets.
Clarinets other than the standard B♭ and A clarinets are sometimes known as harmony clarinets. However, 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. See separate articles for additional details.
