Take a deep breath in through your nose and then slowly let it out through your mouth, making a "sigh" sound. As you do this, imagine that you are opening up the back of your throat and allowing the air to flow freely.
2. Gargle with warm water.
This can help to relax your throat muscles and improve circulation, allowing for better airflow.
3. Practice tongue trills.
Place the tip of your tongue behind your bottom teeth and vibrate your tongue against the roof of your mouth. Do this until you feel a stretch at the base of your tongue and throat.
4. Sing at a comfortable volume.
Avoid straining your voice, and remember that it's okay for your throat to feel open and relaxed, even when singing at a low volume.
5. Experiment with vowel sounds.
Different vowel sounds require different positions and movements of the mouth, throat, and tongue. Try singing different vowels (e.g., "ah," "ee," "oh," "oo," "eh") to find the positions that create a sense of openness and resonance in your throat.
6. Practice diaphragmatic breathing.
Using your diaphragm to support your breath gives your throat a better place to rest. When you sing with a tight throat, you are more apt to strain because you are squeezing the muscles in your neck that close the airway.
7. Take regular vocal rest.
Avoid putting excessive strain on your voice, and take regular breaks from singing to allow your vocal cords to rest and recover.
8. Work with a vocal coach or voice teacher.
A trained professional can help you assess and improve your vocal technique, including throat openness, and can provide personalized guidance and exercises tailored to your specific needs and goals.
