FORGET ABOUT THE TECHNIQUE WHEN YOU SING.
Forget about technique when you sing:
Forget about the technique. Yes, I said it.
It is important that you remember singing technique is something we practice in order to become free to sing whatever we want to express.
When we work on song interpretation (and when we perform), the story is important. Not technique.
If technical issues are hindering you from giving your story or performance the expression you would like to have, then of course you need to work on those. Technique needs to be practiced into a habit, so that we can use it while we perform. But that’s another story.
Singing technique is just a tool to help you express what you want, and to keep you healthy while singing.
Singing technique can help you express whatever you want.
But if there is no expression in the first place, there is no singing technique in the whole world that can help you.
