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.

Be in the moment:

Know your story, your Sender, Receiver, goal, and so on.
But allow the story to unfold itself in the moment.Try to not fix an ending to your story, that would only make your performance boring. Keep it open. Play with it.In real life, do we ever know exactly what is going to happen next? No we don’t.So go from moment to moment, just as you would in a real-life situation. 

Don’t try to ‘get it right’:

When you work on interpretation, don’t focus on the performance. Don’t focus on ‘getting it right’. Focus on the story. The moment you try to ‘get it right’, it becomes difficult.And needless to say, all the voices in your head saying “I wonder what they think of me” have to be turned off.

TIP FOR BECOMING A POSITIVE LISTENER.

I would like to share with you a tip for becoming a positive listener as a musician.
It’s a simple and powerful strategy, you document and keep track of all the positive feedback and comments you receive (about your singing, or sometimes even about other things).
Keep doing this at least for one month.
This is especially good for people whose ‘Inner Critic Voice’ has become way too loud.
In case you wonder if your ‘Inner Critic Voice’ has become too loud, you’ll recognize this, if people tell you they loved your show, if you keep being booked to do the job again and again, if your vocal coach tells you what you’re doing is great, people in your audience are touched or moved to tears or similar things…but you still can come up with 1000 reasons why you are not satisfied with anything at all about your singing.
