Hello ladies and gents!
Here is my newest video explaining how to approach and use a mixed voice. Mixed voice means singing "between" chest and head voice by accessing your nasopharynx (which lets the sound vibrate in the "mustache" region of your face). Accessing the mixed voice technique itself is not super complicated, but sometimes using muscle memory to master it can be tricky. This video explains some simple exercises that will help you practice.
Let me know if this video helps you access you vocal mix!
