What is a falseto in singing?

In singing, falsetto is a vocal register produced with reduced vocal fold involvement compared to the chest register or modal voice. This results in a bright, light, and airy vocal quality. To produce falsetto, the vocal folds are brought together less firmly, leaving a small gap for air to escape between them. The sound produced is characterized by a higher pitch and reduced vocal weight compared to the chest voice.

Falsetto is commonly used in classical, pop, and R&B singing, often as a way to extend the vocal range and achieve specific tonal effects. The tessitura (comfortable vocal range) of the falsetto is generally located above the passaggio, a key transition point in the voice where there's a shift from the chest voice to the higher registers.

It's essential for singers to develop control, balance, and fluidity in transitioning between their full voice and falsetto to use the falsetto effectively in singing. Vocal training and proper technique can help to refine the falsetto, making it a versatile and dynamic part of one's vocal range.
