Really great question and relevant to what I’m doing at the moment with an 8 year old! She is my youngest at the moment and while I adore her natural, sweet “high larynx” sound, I am trying to get her to practise dropping the larynx (using the yawn) in order to achieve a warmer, deeper tone. She sort of gets it, but finds it weird and funny! I am not too worried about it at this stage, as this will happen naturally as she gets older. I don’t know whether to push it; we are only at the start of lessons so perhaps I’ll see if I can re-introduce this idea in a different song choice. Something jazzy maybe. Would be really interesting to hear other teachers’ views on this!
