Sing until you are sure which notes prompt you to switch. This will vary depending on how high or low your individual voice is.
Your nasal tone should sound like a fire truck or even like a baby crying, which may seem odd, but it will strengthen your ability to bridge the break point. As your ability to sing in mixed voice improves, the nasal tone can eventually give way to a blended, pleasant tone by listening to yourself to notice how it sounds. So you culture/cultivate your voice by practicing your blending so your voice is not either head or chest but a blended voice much of the time. [2] X Research source Modify your vowels. Vowels work differently in head and chest voices. If you try to force your vowels to remain consistent across your register break, you will not achieve middle voice. Sing elongated vowels gently across your break, and notice where they naturally change. A long “i” (as in “sigh”) will become a short “i” (as in “trip. “), etc. Begin blending voice before you hit the hard break point. Don’t try to jump into your other voice. Rather, realize you’re approaching a change to head voice while notes are rising but you’re still comfortably below your break upward in the notes. Also, begin blending as you’re approaching the shift to chest voice notes while you are still above your break point.
“Gug” on a low note in your range, and continue singing “gug” up and down through a major arpeggio (each of the notes of a major chord sung separately). Sing “Mum” in the same manner. So, your larynx tends to strain to rise as you sing higher notes, but to get to your mixed voice you will want it to stay lower even as you climb to higher notes into the nasal/head voice. Don’t force/strain your larynx. Sing the tones patiently into their place.
Keep your tone even, and go slowly. Don’t rush the difficult notes. You will naturally blend your head and chest voices if you sing below and above your register break without changing your tone. Play along on a piano as you sing, or sing along to a recording of vocal exercises. You can easily find free recordings of 5-note chromatic scales for vocal exercise online.
Use this exercise regularly. The beginning of your routine is a good time for it, as it warms up your mouth. Do your trills for a scale longer each time. When singing using your chest voice, focus on not straining your throat.
