Over many years of vocal training I have found that, often, vocal challenges are not about the voice but about the management of sung text. As an actor who sings you have a responsibility to ensure that your words are intelligible to the audience, even when you are singing a ballad. Sung text requires careful handing because it is easy to lose words or meaning when sustained pitch and a defined rhythmic structure are called for by the music. By focussing on the mechanics of forming the vowels and consonants you will become more involved with your text and story.
