Blind musicians are singers or instrumentalists who are physically unable to see. In many cultures, blind people have become musicians in disproportionate numbers.Several theories have been advanced as to why the profession of musician is a popular one for the blind.

There has long been a folk belief that blind people can hear better than sighted people, and that therefore the blind have an advantage when performing music. Some recent studies have supported this belief. For example, research has shown that blind musicians are more likely to have perfect pitch than sighted musicians  Similarly, a paper published in Nature in 2004 found that people born blind or who went blind early in childhood were better able to recognize variations in pitch than were sighted people.

People who went blind later in life had no advantage over those who could still see. The research team believed that this suggested differences in early brain development between those with sight and those who lost their sight in their early years. Specifically, they thought that in those blind from childhood the visual cortex, usually used for processing visual images, might be used for processing sound and other sensory input instead.
