Blasting, often referred to as screaming, is a vocal technique used primarily in heavy metal and hardcore music. It involves producing a harsh, powerful sound that can convey intense emotions. This technique is achieved by manipulating the vocal cords and using breath support, allowing singers to create a distinct, aggressive tone without damaging their voices. Screaming can be categorized into various styles, such as death metal growls or black metal shrieks. Each style has its own unique characteristics and techniques. Proper training and practice are essential for vocalists to master blasting while maintaining vocal health and avoiding strain.
