The limit of human treble varies from person to person, but it is generally accepted that the limit is around C5, which is the high C of male voices. This limit is limited by the physiological structure and tension of the human vocal system. Specifically, the vocal cords themselves have a limited amount of tension, and there are limits to the way people produce vocalizations dominated by the thyroarytenoid muscle. Therefore, the limit of the human treble depends mainly on the tension limit of the thyroarytenoid muscle.
Humans have been trained to expand their high vocal range of about two tones. In other words, the upper treble is about G4, while the upper limit of all registers is B4. As for the highest vocal range of the mix, it is usually almost an octave upwards, depending on how well the thyroarytenoid muscles are at least slightly retained. As a result, baritone remix can reach the upper limit of G5 to A5, while tenor can even reach B5.
Also, it is worth noting that there are reports that the limit of human treble has reached C8, which is equivalent to the highest note of a piano. However, this treble usually requires special training and skill to achieve, and may require amplification with the help of electronics. Therefore, while the limit of human treble may theoretically reach around C8, in practical application the generally accepted limit is still around C5.
The existence of the human treble limit is of great significance for vocal training and performance. Knowing the treble limits can help vocal teachers and students clarify their training goals and avoid vocal cord damage caused by overtraining. In addition, by understanding the limits, teachers and students can train more specifically to further improve the expressiveness and technique of the voice.
When it comes to creating and performing, it also makes sense to know the limits of treble. Composers and singers need to consider the factor of treble limit in their composition and performance, and use treble reasonably to enhance the artistic effect of their works. Avoid overusing treble in your compositions to avoid sound fatigue and damage.
In summary, the limit of human treble is limited by the physiological structure and tension of the vocal system. Although it is possible to develop the high vocal range with training, care is still needed to treat the vocal cords. Understanding the limits of treble helps to properly develop vocal training, performance, and composition, thereby protecting our voices and enhancing their expressiveness.
