Put simply Incorrectly engaging the Constrictor muscles when we sing sets up a vicious circle where the outcomes are always going to be the same:ī. Waking up the constrictor muscles is not the best idea when you sing, because it automatically reduces the internal diameter of our throat and significantly reduces the size of the resonating spaces (think, various mini amphitheatres or sound board areas) inside our throat whose job it is to naturally amplify and add rich over tones to our sounds when ever we vocalize. When you incorrectly sing this way, you’re going to automatically wake up the neighbours i.e. That’s what happens when you use the big bulky muscles of the throat to support your vocal production. Regardless of your current level of singing ability, I am sure you will have experienced the frustration of going all out to sing a middle or high note with power and as you begin to produce the note or the scream you notice a feeling of tightness or squeezing in the back of the throat and correspondingly your voice simultaneously looses much of its dynamics, volume, tone etc and begins to sound small and choked off? If it has happened to you before on stage, or during a performance you will know exactly what I am describing and the negative effects it can have on your confidence as a performer. Very fitting for my first post for 2016, as it’s a big subject lots to tackle and its vital need to know info for every singer! Glossopharyngeal nerve Glossopharyngeal part of the superior pharyngeal constrictor muscle Lingual branch Palatoglossus muscle Palatopharyngeal muscle Stylopharyngeal muscle.This Rapid Vocal Results, blog addresses, the mechanics of how constrictor muscles work and how they can negatively impact on our vocal production. ![]() The simultaneous contraction of the palatopharyngeal and palatoglossus muscles on the pharyngeal stage of deglutition may aid in the passage of bolus from the oral cavity to the midpharyngeal cavity by increasing pharyngeal pressure. These neuromuscular arrangements may suggest the presence of specialized constrictive movements of the midpharygeal cavity at the level of the base of the tongue with the retrusive movement of the tongue. We observed that, after branching to the stylopharyngeal muscle, the lingual branch of the glossopharyngeal nerve branched to the glossopharyngeal part of the superior pharyngeal constrictor muscle, the palatopharyngeal and the palatoglossus muscles before inserting into the space between the muscle layers of the superior and middle pharyngeal constrictors. Nerve fiber of the lingual branch of the glossopharyngeal nerve (main root of the glossopharyngeal nerve) was examined by the use of a binocular stereomicroscope. Six en bloc samples (9 sides), including the tissue from the skull base to the hyoid bone were obtained from adult human cadavers. The purpose of this study is to identify the contribution of the lingual branch of the glossopharyngeal nerve to the neuro-motor control of three muscles: the glossopharyngeal part of the superior pharyngeal constrictor muscle, the palatopharyngeal and the palatoglossus muscles. ![]() This group of muscles constrict the midpharyngeal cavity during retrusive movement of the tongue. Fibers of the glossopharyngeal part of the superior constrictor muscle are connected with fibers of the transverse lingual muscle, forming a ring of muscle at the base of the tongue.
