When singers sound like they're crying or exhibit a noticeable emotional quality when hitting high notes, it is often referred to as "vocal cry" or "cry vocalization." This vocal technique can add depth, expressiveness, and intensity to a performance. Several factors contribute to this effect:
Emotional Expression: Singers often use vocal techniques to convey emotions in their performances. When reaching high notes, the intensity of the emotion may increase, leading to a sound that resembles crying.
Pharyngeal Resonance: Singing with a pharyngeal resonance involves creating a vocal sound that resonates in the pharynx (the upper part of the throat). This technique can add a "cry-like" quality to the voice.
Constriction of the Cricothyroid Muscle: The cricothyroid muscle, located in the larynx, is responsible for controlling the tension of the vocal folds. When singing high notes, some singers may use this muscle to increase tension and create a more emotional, intense sound.
Mix Voice: Singers often use a mix voice technique when transitioning to higher notes. This involves a balance between the chest voice (lower notes) and the head voice (higher notes). The mix voice can add a touch of vulnerability and emotional resonance to the sound.
Airflow and Dynamics: Singers may adjust their airflow and dynamic level when hitting high notes. This can create a sense of vocal vulnerability and contribute to the "cry" effect.
Cultural Influences: In some vocal styles, especially in certain genres of music, emotive vocal techniques like vocal cry are highly valued and are incorporated intentionally to convey strong emotions.
It's important to note that not all singers intentionally use cry vocalization, and the effect can also occur naturally based on individual vocal characteristics and emotional connection to the song. Some singers may naturally produce sounds that resemble crying when singing high notes due to their unique vocal timbre and emotional sensitivity.
Overall, cry vocalization is a stylistic choice and can be a powerful tool for singers to evoke emotions and connect with their audience on a deeper level. However, like any vocal technique, it should be used judiciously and with proper vocal training to avoid strain or damage to the vocal cords.
