This physical exercise relive puberphonia.
Voice should come from uvula,not laryx.
What are the manipularion in the mouth and neck.
Try this quick tip to get your sound LOUDER and EASIER: Imagine you are squeezing two oranges underneath your armpits. You should feel some engagement in your pectorals (in front) and lats (in back). Sing a line of a song with and without this engagement.
Why this works:
A lot of singing deals with displacing tension, so that your larynx and vocal folds are free to move as needed. By engaging these lower muscles you are deactivating some of the laryngeal musculature which allows for more freedom in the airways. This trick works especially well for belting but can be useful for other styles!
Velum Control: This figure trains the velum (also known as the soft palate).. This structure controls how nasal the sound is An open or partially open velar port filters out high frequencies and can soften the tone. A closed velar port allows no sound through the nose thus the voice tends to be brighter and more full.
Larynx Control If you’ve ever blown across the top of a bottle you probably noticed that as the bottle empties the note is lower in pitch. This is because lower notes need a longer resonator (empty bottle) while higher notes need a shorter resonator (fuller bottle).
The larynx usually lowers for low notes to make the vocal tract longer and raises for high notes to shorten the resonator. We can however consciously change the larynx height to effect the tone quality. This figure trains raising and lowering of the larynx. A lower larynx produces the darker sound featured in classical singing but can be used any time a richer sound is required. A higher larynx brightens and “thins” the quality of the voice.
