What are some of the techniques that rappers can use to develop a clear and distinct tone when singing?

There are several techniques that rappers can use to develop a clear and distinct tone when singing. One technique is to focus on proper breath control and diaphragmatic support, which can help to create a stable and consistent tone. Rappers can also work on developing a clear and consistent vibrato, which involves a slight oscillation of the voice that adds depth and character to the tone. Another technique is to practice proper vowel shaping, which involves shaping the mouth and tongue in specific ways to produce clear and distinct vowel sounds. It's also important for rappers to focus on proper resonance and projection, which involves using the proper amount of breath pressure to project the voice and create a full, rich tone. Additionally, experimenting with different microphone techniques and recording equipment can help rappers to fine-tune their tone and achieve a clear and distinct sound that's uniquely their own.
