If you keep breaking the pitch while singing high notes, it could be due to some of the following reasons:
1.Incorrect breathing: If you don't have adequate air support to sing high notes, the vocal cords may become tense, causing the voice to crack. Make sure to do proper breathing exercises before singing the high notes, using abdominal breathing to support the high notes.
2.Position of the sound: If the sound is not positioned correctly, such as if the sound is too front or back, it can cause the treble to break. To make sure your voice is in the right position, consult with a vocal teacher to help you find the right sound position.
3.Excessive force: Some people use too much force when singing high notes, which can lead to tension and rupture of the vocal cords. Try to relax your vocal cords without exerting too much force.
4.Lack of training: Singing high notes is a skill that requires skill and training, and it may take you more practice to gradually improve your vocal range and technique.
5.Inflammation or fatigue of the voice: If you feel inflammation or fatigue in your throat, it is easy to break the sound when singing high notes. Make sure your throat is well rested and protected.
The most important thing is to seek guidance from a vocal teacher. They can help you find out what problems you may have when singing high notes and provide you with professional training and advice. Don't overexert yourself, practice patiently and slowly improve your vocal range and technique.
