INTRODUCTIONSinging in psychotic patients has received little attention in the psychiatric literature. In this preliminary study, we test the hypothesis that manic patients sing more than schizophrenic patients (SPs).

MATERIALS AND METHODSManic patients and SP inpatients and outpatients were interviewed using a semi-structured questionnaire which included questions on musical interests, and how much they felt like singing prior to their most recent admission to hospital. They were asked if they were willing to sing during the interview and responses were observed.

RESULTSOf the 69 manic patients and 68 SPs interviewed, manic patients were more likely to report singing than SPs (76% vs 24%) prior to their most recent admission to hospital. There was a trend for manic inpatients to be more willing to sing during the interview.

CONCLUSIONIncreased singing is suggested as a useful symptom and sign in patients suffering from a manic illness.
