Hi! Hope everyone is doing well. I have noticed recently that I have trouble singing the "e" vowel. It doesn't sound as resonant as other vowels, and tend to be a bit shaky as well as doesn't sound smooth transitioning. I suspect this is because I couldnt lift the soft as well as when I'm singing other vowels. 

Do you have any advice to improve this? Thank you and have a nice day!

We often end up modifying the EE vowel to more of an IH by dropping the jaw! Give that a try.
