How to Sing in Mixed or Middle Voice. Ask any accomplished singer and he or whe will tell you that perhaps the most difficult register to master is the mixed or middle voice. A singer must learn to blend the head and chest voices to create a pleasant sounding middle register. With some practice and these pointers, you can learn to sing in your mixed or middle voice as well.
Sing lots of scale exercises at the very top and bottom of your vocal range. Notice which notes you typically sing in your chest, or lower, voice and which you sing in your head, or high, voice. You'll find that there are a few notes in between that you have a difficult time identifying.
Identify your vocal break or bridge. These are the notes you have a difficult time singing clearly and comfortably in chest or head voice. This range will be at the heart of developing your mixed or middle voice.
Experiment with different vocal exercises singing the notes in your break or bridge range. Try each note on different vowel sounds like "ah" "oh" "ee" and "oo." Take note of the vowel sounds that create easy and natural placement for these notes.
Vocalize with the vowel sounds that created natural placement and resonance in your break or bridge zone. Find your middle voice by gradually moving the notes in the lower end of the range up and out of the chest and more into the mask of your face. For the higher notes in the break range, focus on moving their placement from the head voice to the front of the mouth. Placement of the middle voice is key to creating good resonance.
Add words to the sounds you are creating and eventually incorporate them into full melodies. It will take a lot of practice to find your middle voice and to know which notes in a song you should sing in the mixed voice. Eventually, you may find that you begin to use your middle or mixed voice so often that the transition between chest, middle and head voices becomes seamless.
Find a qualified voice teacher or vocal coach to help you find your vocal break. Practice humming or lip buzzes on notes that fall into your vocal break to grow accustomed to the feeling of sound resonating in the mask of your face.
Don't try to oversing in your middle or mixed voice. It is very tempting for many singers to confuse using the middle voice with tense, throaty singing. You should never feel any discomfort or tightness in your throat when singing in any register. Engage your vocal chords completely before trying to sing in your middle voice. If you don't press the chords together fully, air passing through can potentially cause damage. You can accomplish this by mentally envisioning the note before you sing it, practicing good breathing techniques and warming up properly.
