Many people want to be able to sing in the high register, but singers need to be able to sing in the low register as well. Many singers want to learn how to make the voice darker and deeper, almost like the lyrical one. In fact, by doing it naturally you will be able to emit the high and low notes. These steps help to get a darker voice.
Steps
Step 1. Practice the 'u' (think of the word 'bURRO')
It is an excellent way to lower the larynx, which is crucial for achieving a 'dark' and 'deep' sound. Start from a medium sound and arrive at the lowest sound you can make by tying the note and using the vowel 'u' (as if you were saying 'uuuuuuuu!'), Repeat the procedure starting from a note in the lower middle register.
Step 2. When he has learned to do this, repeat the exercise starting with a high volume and decreasing in volume as you reach the low notes
When you are in the lower part of your register, the notes must be less loud than those of the middle register, because the vocal cords are so relaxed that a loud volume would interrupt them.
Step 3. Another way to sing the low register sounds is to use a crackling-like vocal effect (like that of the ghost from The Grudge movie) while doing it
This effect relaxes the vocal cords and helps you with low sounds. You can progressively sing lower and lower, using this effect before outputting the sound.
Step 4. When you can sing the low notes well, you can apply the position of the throat and larynx to the middle register
The vowel 'u' causes the throat to widen and the larynx to lower. Beginning at the bottom, sing an arpeggio moving up and then down again with a soft, staccato 'bo' sound. Slowly eliminate breathlessness and increase volume while always keeping the larynx relaxed. Repeat the procedure, progressively starting with the high notes of the low register.
Step 5. Now try the same exercise with the vowel 'u' tied, but without wheezing
Air pressure should come from the diaphragm, not the throat. As you go up, turn up the volume to sing the higher notes clearly but without 'forcing' the larynx down. The high notes must 'vibrate' inside the ears (check by placing your hands over your ears as you sing).
Step 6. Do not strain the larynx
When you get to the high end of your register, the notes will be 'clearer'. Don't force the larynx down or you'll get a muffled sound, just let things go naturally. However, don't open your mouth too much or the sound will be tinny and aggressive. Hold your mouth with an oval opening and lift your upper lip. This will serve to achieve a dark sound, while maintaining the 'vibrations' of the low register.
