Belting is a vocal technique used primarily in musical theater and popular music, characterized by a powerful, resonant sound produced in the singer's chest voice. This technique allows singers to project their voices over an orchestra or band without straining, making it ideal for performances in large venues. To achieve belting, singers engage their diaphragm and maintain proper breath support while using a mix of chest and head voice. This technique is often associated with styles like Broadway and pop music, where emotional expression and vocal strength are essential for conveying the song's message.
