Falsetto is a vocal technique that allows singers to produce notes higher than their normal range. It involves using the vocal cords in a way that creates a lighter, airier sound. This technique is often used in various music genres, including pop, classical, and R&B, to add emotional depth or highlight specific parts of a song. Singers typically use falsetto when they want to reach high pitches without straining their voices. It differs from head voice, which is a fuller sound produced in the upper vocal register. Famous artists like Prince and Freddie Mercury are known for their impressive use of falsetto in their performances.
