Mixed voice is a term you have likely ran into if you study vocal technique from youtube. There isn´t exactly agreed upon meaning for it, but usually vocal coaches seem to use the term to refer to something that helps you get those high notes without flipping to falsetto. On this video I share some thoughts on it and some exersices that can help you get started.

Some of the exercises are pretty close to typical Speech Level Singing (SLS) exercises. I happen to think that SLS gives pretty nice basis for learning mixed voice and deserves much credit for it. I did not feel the need to go through them in much detail, since everyone can find them very easily on youtube. Instead, I focus more on couple of other exercises that I have not seen being used but are highly efficient for learning mixed voice.
