The empirical literature on auditory imagery is reviewed. Data on (a) imagery for auditory features (pitch, timbre, loudness), (b) imagery for complex nonverbal auditory stimuli (musical contour, melody, harmony, tempo, notational audiation, environmental sounds), (c) imagery for verbal stimuli (speech, text, in dreams, interior monologue), (d) auditory imagery's relationship to perception and memory (detection, encoding, recall, mnemonic properties, phonological loop), and (e) individual differences in auditory imagery (in vividness, musical ability and experience, synesthesia, musical hallucinosis, schizophrenia, amusia) are considered. It is concluded that auditory imagery (a) preserves many structural and temporal properties of auditory stimuli, (b) can facilitate auditory discrimination but interfere with auditory detection, (c) involves many of the same brain areas as auditory perception, (d) is often but not necessarily influenced by subvocalization, (e) involves semantically interpreted information and expectancies, (f) involves depictive components and descriptive components, (g) can function as a mnemonic but is distinct from rehearsal, and (h) is related to musical ability and experience (although the mechanisms of that relationship are not clear).

The current study explored the music perception ability of individuals diagnosed with schizophrenia and its relationship with other cognitive abilities and psychotic symptom severity. The persons with schizophrenia performed significantly worse than the control group on the Montreal Battery of Evaluation of Amusia (MBEA) (p<0.001). The music perception ability of persons with schizophrenia was related to other cognitive abilities (attention, verbal memory, spatial memory, and executive function) and the severity of psychotic symptoms.

Music is a highly versatile form of art and communication that has been an essential part of human society since its early days. Neuroimaging studies indicate that music is a powerful stimulus also for the human brain, engaging not just the auditory cortex but also a vast, bilateral network of temporal, frontal, parietal, cerebellar, and limbic brain areas that govern auditory perception, syntactic and semantic processing, attention and memory, emotion and mood control, and motor skills. Studies of amusia, a severe form of musical impairment, highlight the right temporal and frontal cortices as the core neural substrates for adequate perception and production of music. Many of the basic auditory and musical skills, such as pitch and timbre perception, start developing already in utero, and babies are born with a natural preference for music and singing. Music has many important roles and functions throughout life, ranging from emotional self-regulation, mood enhancement, and identity formation to promoting the development of verbal, motor, cognitive, and social skills and maintaining their healthy functioning in old age. Music is also used clinically as a part of treatment in many illnesses, which involve affective, attention, memory, communication, or motor deficits. Although more research is still needed, current evidence suggests that music-based rehabilitation can be effective in many developmental, psychiatric, and neurological disorders, such as autism, depression, schizophrenia, and stroke, as well as in many chronic somatic illnesses that cause pain and anxiety.

Investigation of acquired amusia caused by brain damage suggested that cortical lesions of the right hemisphere contributed to musical deficits. We previously reported reduced musical ability in schizophrenia; these deficits were correlated with clinical manifestations such as cognitive dysfunction and negative symptoms. However, the neural substrate underlying the musical disability in schizophrenia remains unclear. We investigated the relationship between musical deficits and cortical thickness in patients with schizophrenia using structural MRI. We recruited 24 patients (13 males; age mean=45.9years old), and 22 controls (14 males, age mean=43.5years old). Musical ability was assessed with the Montreal Battery for Evaluation of Amusia (MBEA), cognitive function with the Brief Assessment of Cognition in Schizophrenia (BACS) and clinical features of illness with the Positive and Negative Syndrome Scale (PANSS). MRI Images were acquired and processed using FreeSurfer. Surface-based analysis showed that thinner cortex in left temporal and inferior frontal region was associated with lower musical ability in schizophrenia. In contrast, in controls thicker cortex in the left supramarginal region was correlated with lower musical ability. These results shed light on the clinical pathology underlying the associations of musical ability, cognitive dysfunction and negative symptoms in patients with schizophrenia.
