How are you supposed to sing with your soft palate raised (like when you yawn)?

Question

Yeah, I kind of find that difficult to do.

Answer 1

It seems like you're trying to make room in your mouth. Keep your mouth in a vertical position, like all your vowels are originating from the letter "O". Tuck in the corners of your mouth. Relax your tongue and rest it on the space at the bottom of your mouth, behind your lower gumline. Open up your throat when you sing, much like when you drink.

Try a humming vocal exercise. Hum a series of notes while applying the stuff in the paragraph before this. You know how acoustic guitars are hollow and have that hole in them? That's the purpose of the room in your mouth. Let the sound resonate or vibrate in that space. Then, after a certain amount of time, switch to the syllable "YOH", but don't forget to keep applying the techniques.

Answer 2

drop your jaw and enunciate every syllable when you sing

Answer 3

Open your mouth largely and keep your chin downwards, I think...

Answer 4

Just imagine an egg is in your mouth.  Always sing on the AH vowel position. Good luck:)
