Extreme vocal techniques for producing distorted sounds in rock and metal singing

International audienceRock and metal singing utilize distorted sounds for aesthetic and expressive purposes. What are the vocal techniques that are used to safely produce screams, growls, and yells in distorted singing? What are the laryngeal structures that are implied into such voice production?This workshop aims to provide some insights into several extreme vocal techniques that are used by professional rock and metal singers, exploring the physiological behavior related to several specific sounds (distortion, false cord, fry scream, whistle fry, growl, yell scream, tunnel throat, guttural) by means of laryngeal endoscopy combined with breathing plethysmography, electroglottography and acoustic assessments. The sounds will be illustrated, and some clues for teaching them will be given. The physiological correlates will be detailed and discussed. The contributions of vestibular and aryepiglottic folds will be shown
