What’s really happening inside the larynx when we ‘tilt?’ In this episode, Alexa is joined by voice researcher Dr Mathias Aaen to unpack the science behind thyroid tilt - exploring what his latest studies reveal about pitch, vocal fold lengthening, and healthy singing. The pair cut through common misconceptions, translate research into studio-ready language, and ask the big question: are our teaching prompts actually doing what we think they are? If you love practical pedagogy grounded in solid science, this one’s for you.
