"The first one is the NG exercise. Start by humming ng, like at the end of the word sing. Focus on keeping the sound forward in your face and not letting it drop into your throat. While holding the NG ng, you can gently open into different vowels like e, a, and a, while keeping the same bright placement. This trains your voice to stay lifted and helps build resonance into a more feminine range. e, a, a The second one is the tongue out a exercise. Stick your tongue out slightly and say the ah vowel like in the word bad. Keeping the tongue out prevents tension in the back of the throat and encourages a clearer, less muffled tone. It also helps you avoid slipping back into a deeper chest to your sound. Doing these separately has been incredibly effective for me. I usually practice each for 5 to 10 minutes a day. The improvements in brightness, resonance, and control are noticeable pretty quickly."
