Bareheadella

Bareheadella: noun. A cappella in which no one wears any caps or other headcovers (which, as I understand, is the primary purpose of cappellas). Bareheadellas sing without any musical accompaniment, as cappellas do, with one sole exception: they do not wear any caps or other headcovers. Also, the sole difference between the people who sing in cappellas and bareheadellas is that people who sing in bareheadellas do not mind not wearing caps.
