Good singing is a combination of steady airflow and good shaping for resonance. Consistency in maintaining those parts of the voice is paramount for maintaining good momentum.
But unfortunately, what we know we need to do and our natural reaction aren’t always in line. Singing is also quite psychological. For example, many people find it harder to sing when they’re around others. Or, when they approach the hard part of the song, they hesitate.
This is an issue, because hesitation causes a hiccup in good vocal technique. When we hesitate, we typically “hold our tongue,” which often pulls back into the throat cutting off good resonance. We also tend to slow down our air when we’re uncertain. This is very detrimental to our overall momentum and sound.
I dive into this idea a bit more in this video. Check it out!
