What is falsetto?
Falsetto is the light, breathy register most men flip into above their normal singing range. The vocal folds are stretched long and thin and vibrate mainly along their edges, and they usually do not close completely on each cycle. Air slips through the gap, so the sound is soft, airy and flute-like, with fewer of the upper harmonics that make a voice sound bright and full.
Falsetto is not a "fake" or bad sound, whatever the name suggests. It is a legitimate color used all over pop, soul and R&B: the high lines of the Bee Gees' "Stayin' Alive", Frankie Valli's "Sherry" and Prince's "Kiss" are famous examples. Its limits are power and connection. Falsetto is hard to make loud, it uses breath quickly, and moving between it and chest voice usually produces an audible flip.
