Coup de glotte

Coup de glotte is a term used in both the medical and vocal music fields, referring to a specific type of vocal articulation or attack. In the medical context, it relates to the sudden closure of the glottis (the space between the vocal cords) which can have implications for breathing and vocalization. In vocal music, it describes a technique used by singers to initiate sound with a pronounced glottal stop. This article will explore the concept of coup de glotte from both perspectives, highlighting its implications, techniques, and considerations.

Medical Perspective

From a medical standpoint, coup de glotte involves the abrupt closure of the glottis, which can occur voluntarily or involuntarily. This action can impact breathing and voice production, leading to potential issues if not properly managed.

Causes

Coup de glotte can be caused by various factors, including:

• Laryngospasm: An involuntary spasm of the vocal cords that leads to a temporary closure of the glottis.
• Vocal Cord Dysfunction: A condition where the vocal cords do not behave as expected, potentially leading to episodes of coup de glotte.
• Emotional Stress: High levels of stress or anxiety can lead to involuntary glottal actions.

Implications

The sudden closure of the glottis can lead to:

• Difficulty breathing
• Changes in voice quality
• Potential for vocal strain or damage if the behavior is repeated over time

Vocal Music Perspective

In the realm of vocal music, coup de glotte refers to a deliberate technique used by singers to start a note with a clear, precise attack, achieved by momentarily closing the glottis before releasing the sound. This technique is often used in classical singing to achieve a specific stylistic effect.

Technique

To perform a coup de glotte, the singer must: 1. Prepare the vocal cords by bringing them close together without touching. 2. Initiate the sound by quickly closing and then immediately opening the glottis, producing a clear, focused onset of sound.

Considerations

While coup de glotte can be an effective artistic tool, it requires careful use to avoid vocal strain. Singers must be trained to execute this technique properly to prevent potential damage to the vocal cords.

Conclusion

Coup de glotte serves as an interesting intersection between medical science and vocal artistry. Understanding its implications from both perspectives allows for a more comprehensive appreciation of the human voice and its capabilities. Whether addressing potential medical concerns or mastering a vocal technique, awareness and proper technique are key to managing the effects of coup de glotte.
