Absolute pitch, also known as perfect pitch, is the ability to identify or produce a musical note without any reference tone. Individuals with this skill can recognize notes played on instruments or sung by voices, often naming them accurately. This ability is relatively rare, with estimates suggesting that only about 1 in 10,000 people possess it. People with absolute pitch can also reproduce specific notes on demand, such as singing a C or playing an A on a piano. This skill is often associated with early musical training, although some individuals may develop it naturally. It can enhance musical performance and composition.
