Answer: Range based exercises done at different volumes and tonal qualities develop the needed balance of vocal fold flexibility, strength and coordination of air flow. This will allow for smoother transitions between registers and easier access to pitches throughout your vocal range. Make sure to begin with flexibility exercises to warm up your instrument and stay hydrated.
Answer: “Cracks” or “breaks” happen when the vocal folds adjust from one register to the other. These “cracks” don’t cause any harm to your vocal folds, but if you experience pain or strain, chances are, you’re pushing too much. Try doing range based exercises focusing on your passaggio to help smoothen the transition between registers.
Answer: The “mixed” voice or “passaggio” is where the vocal folds adjust between two registers. Range based exercises are going to help you with the transition between registers and give you the ability to sustain notes in that “mixed” voice.
Answer: “Belting” is the result of intentionally staying in the chest voice beyond its original threshold by putting more air pressure on higher notes within the chest voice. Range based exercises done at higher volumes will help develop this skill. Make sure to follow the Guidelines for safe and effective vocalizing.
Answer: When you’re not able to sing in head or falsetto voice you could either be adding too much air pressure underneath the vocal folds or your vocal folds aren’t able to stretch enough to produce a sound in those registers. Make sure to warm up with flexibility based exercises and consider the general health of your vocal instrument before adding range exercises.
