On this video clips you see ENT doctor Julian McGlashan from Nottingham University Hospital endocpying CVI teacher On this video clip you see ENT doctor Julian McGlashan from Nottingham University Hospital endoscopying CVI teacher Julie Lindell. To the right from Julian you see CVI teacher Camilla Bogulski who is monitoring the sound recording and the endoscopy recording.

You see the videoscope being inserted in Julie’s left nostril and we follow its way through the nasal cavity, past the uvula and entering the oropharynx, where we see the back wall of the throat and the back of the tongue until it ends just above the larynx. Here we have a great view of the piriform fossa, the posterior pharyngeal wall of the hypopharynx, the arytenoid cartilages/cuneiform, the epiglottis, the aryepiglottic folds, the ventricular (false) folds and the vocal folds. (see ‘Anatomy & Physiology’ for identifying these parts of the larynx)

From here we can see the movement of the vocal folds and all the involving laryngeal gestures. This position and the endoscopy recordings from here provides us with a good overview of what is happening when we speak and sing.

(See ‘Vocal Modes’, ‘Transitions between the modes’ and ‘Effects’ for further details).
