I am excited to share with you my recent interview to The Telegraph (https://www.telegraph.co.uk/health-fitness/body/adeles-transformation-singer-slimmed-changed-up-look/) After Vasili Karpiak, an opera singer who has worked with the Royal Opera House, lost weight he found his voice changed. “I realised it’s not my voice any more and I need a different technique.
“The voice does change [when you lose weight], simply speaking from physiology. The body has one size and the vibration, the sound and colour is applicable to that size, when you lose a lot of weight you get a different colour.
“You get a different space for the sound frequencies that are created as a result of the vocal cords, there is less space for the vibration process.”
However, it’s not all bad news: “The stamina of the voice will increase, and if anything I think it has a positive influence on the artist.”
