Musical hallucinations. A historical and clinical study.

A sample of 46 subjects experiencing musical hallucinations was analysed - 10 new cases in addition to 36 culled from the literature. When compared with controls, it was found that musical hallucinations are far more common in females, and that age, deafness, and brain disease affecting the non-dominant hemisphere play an important role in their development. Psychiatric illness and personality factors were found to be unimportant.
