How can rappers expand their vocal range and improve their ability to hit high and low notes?

Rappers can expand their vocal range and improve their ability to hit high and low notes by practicing regularly and incorporating specific vocal exercises into their routine. One effective exercise is called a lip trill, where the rapper blows air through pursed lips to create a vibration, which helps to loosen up the vocal cords and increase flexibility. Another exercise is the "siren," where the rapper smoothly transitions between their highest and lowest comfortable notes. It's important to start with exercises that are within the rapper's current vocal range and gradually work up to more challenging notes. In addition to vocal exercises, rappers can also benefit from listening to and studying the singing techniques of other artists, as well as experimenting with different styles of singing to find what works best for their voice. Consistent practice and patience are key to expanding vocal range and hitting high and low notes with confidence and accuracy.
