- Closed vowels, such as the vowel sounds in the word mom, eat and did are easier to sing than words with open vowel sounds such as hat, cat and that. Practice singing scales with words instead of notes. The words you sing have a great deal to do with the difficulty you experience hitting notes--especially higher notes. By practicing your scales and replacing the notes with words that have a closed vowel sound, you can exercise the muscles it takes to coordinate movement to wider sounding vowels. After you have practiced singing words with a closed vowel sound, try singing vowels in place of notes in a scale.
- Put your hand between your navel and your last rib. Gently press in as you sing a note. You'll hear the note begin to change pitch. Now apply and release pressure in this area. Do it quickly. You'll hear the note you're singing begin to vibrate. This area is the key to singing vibration. Try singing a scale as you quickly push up and down in the diaphragm area until you feel you can control this vibrato on your own.
- Learn to recognize when you are in key. Sit at a piano or use another instrument to provide reference notes. Find a quiet room and play the notes of any scale separately, trying to match each note. When you aren't singing in tune, you will hear a vibration between the note you play and the note you sing. The farther away from the correct pitch you are, the quicker those vibrations will sound. Those are the two conflicting pitches colliding. The closer you come to being in tune with the note you're playing, the slower those vibrations will become. When you match the pitch, the vibrations disappear completely.
Try purposely singing too low and out of key when you play a note. Listen for the vibration and bring your voice up until you hit the correct pitch. Do this several times with each note in a scale. Try doing it in different keys. Once you feel yourself naturally bringing your voice in tune with your reference notes, try playing an entire scale and singing each successive note before you play it. - Learn to recognize what it feels like when you sing a high note or scream. You'll feel your diaphragm working and your breath as it enters and exits your body. Each singing technique you use will feel the same way each time you use it. Recognizing how it feels when you are singing correctly will help you recreate those proper techniques and execute them properly.
