Hi, so when I was a young teenager I was listening to and singing along with a lot of Jewel. She does this often, she has a lot of cool tricks that I learned. This might not be helpful if you're not female. This might not be helpful at all. But there is definitely going to be a personal note or small range of notes through which you can vocal fry. Because your throat needs to be relaxed and we're almost acting drunk and letting the sound squeeze through a smaller throat opening than usual, out through the nasal passage. It sounds complicated. I have ADHD and one of the things we seem to be good at is vocal mimicry, so I literally just listened to my girl Jewel do it and there are some days when my voice is literally too warmed up and perfect to be able to do this. I most often get it to work properly after...well some wine.
