Good rock singers are able to growl and scream without hurting their voice. The key is to not growl with the modal vocal cord, but to use the false vocal folds that are above the modal cords inside the larynx. The secret to doing this properly is to use: Twang and the Epiglottal Funnel; Stay at the Balance Point.
Twang and the Epiglottal Funnel
Twang is a technical term for the contraction inside your larynx between your epiglottis and the arytenoid cartilages. The sound of twang is not a nasal sound, but a sound that focuses the voice, giving it a helium like quality. By using a lot of twang, you can begin to activate the false vocal folds inside your larynx and get a rock, growly sound without damaging your true vocal cords, the modal cords.
Stay at the Balance Point
When singing Rock, it’s all the more important to follow the rules for the Balance Point:
• Stay loose in your outer muscles
• Keep your mouth open and relaxed
• Activate your pharynx
• Breathe in stomach out
Practice Time : 7 days, 15 – 30 minutes
Warm up with Scale 8 with all the vowels, practice finding some growl in your voice by gradually adding twang. Stop if you need to clear your voice.
