Vocal fold abduction refers to the movement of the vocal folds away from the midline of the larynx, resulting in the widening of the glottis, which is the space between the vocal folds. This action is primarily controlled by the posterior cricoarytenoid muscles, which are the only muscles responsible for opening the vocal folds. Abduction of the vocal folds is a crucial aspect of respiration, as it allows air to flow into the lungs for breathing.

This position is essential for silent breathing and is also employed during certain phonetic sounds that require an open glottis, such as the production of voiceless consonants like /h/ and /f/ in English.
In singing pedagogy, understanding and controlling the process of vocal fold abduction is vital for several reasons:
