I have so many students who love singing songs with high power notes. Now these students I have can always sing these notes quite easily when they are doing their exercises but when it comes to doing it during a performance or even just singing the note during a song in their lesson they go wrong and let's face it, whenever someone sings a Whitney or Mariah song people always wait to see if they can sing that big note at the end and forget about the rest of the song!
One way to conqour these "big notes" is to not focus on the one note - if you do that you are compartmentalising it which will then cause your subconscious to watch out for it which makes you paranoid and unrelaxed which causes you to go wrong - if you think you wont get the note you wont! Instead try to work on the whole phrase around it, sometimes working on your placement just before the note can help. Also when you are performing try to actually visualise yourself getting it - if you can see yourself doing it and let go you almost certainly will get it!
