Here’s part of a question concerning an uncommon vocal problem posted online:
“It’s definitely not a cold. It’s not exactly the same feel of having something physical (for ex. mucus) in the nasal but more like a short duration tense pressure that requires more effort to breathe from the nose after singing high notes. It goes away after a couple of breathes through the nose and comes back right after the high notes again. Of course I don’t breathe from my nose when I sing, but it’s something I notice after I finish a piece or breaks between verses.”
My answer to this post:
You’re pinching off your nasal passages when singing high (the same muscles you would use to “snort” either in or out). They will tend stay in that contracted, pinched position for a little while after the high note passages, just as you described. Some good warm-up exercises to do should include some scales or arpeggios on a hum, but drop the jaw as you sing higher, keeping the lips still touching. This will help release the muscles under the jaw. Humming necessitates the tone naturally releasing through the nose without pinching. Keep the air coming through the hum unobstructed.
Another good exercise type for your issue is to use an “ng” sound on an arpeggio of your choice with a nguh nguh nguh nguh sound. Again, it will keep the “snorting” muscles from engaging.
These should work well for you. Happy Singing!!
