You can learn SO much from watch other people perform. Some questions you can ask yourself while watching any performance.
- How did they show up? (Sloppy? or put together and all glammed up?) 
- Was their first note on pitch? 
- What was their face doing? 
- Did they look like they were having fun? 
- Did you LIKE watching them? 
- Did they make mistakes? If they did, how did they recover? 
Check out Idina Menzel’s performance - Into The Unknown LIVE at the Oscars. In a live performance there is ONE SHOT to do it right. ONE chance to sing your heart out. There are NO do overs during a live performance. So you may as well go BIG or GO home.
