There’s a big difference between the larynx rising and the larynx tilting.
Too much raising of the larynx will only cause you grief. You are basically choking yourself into a squeezed sound with nowhere to resonate.
Tilting the larynx, on the other hand, will allow you to sing in your high register because the cords are being stretched and thinned. Good tilting will actually give the listener the illusion of thicker cords (chest voice).
One of the best exercises for laryngeal tilt is the ‘ng’ sound. Say the word ‘sing’. See how the tongue touches the roof of your mouth. Leave it there. The ‘ng’ will block off sound leaving the mouth. With two fingers, plug your nose to see if you are doing it correctly…. the sound should stop completely.
Now practise this through the break in your voice. Ladies from middle C to high C……..men from A below middle C to A above middle C.
If you can make this sound smooth and consistently through your entire range then the larynx is tilting well!
***Note, the upper range will feel and sound like a whine or whimper. This is necessary to keep the cords closed while ascending.
