Then the rat learns that the reward always comes with the push of the lever. The funny part is, depending on the reward, the rats would often just camp out by the lever and push it over and over. I have seen that rat on stage, singing high notes over and over and over.

Singing high notes is most CERTAINLY an important skill. In fact, when you get to the end of your usable range, you often look longingly and sadly at that next note (the one right past where you are able to sing comfortably).

This is why our company does what we do. We give people not just another note or two...we give them whole blocks of new notes. I personally experienced a full octave and a half of range increase using the 
Singing Success Method.

BUT WHY HIGH NOTES?

That's a question that nobody asks, because it's like asking, "Why would I want more money?" I'm going to ask it anyway because it needs answering. As I've said before, the audience has a reason for being there. They want to be emotionally engaged and they are hoping the singer will take them on that emotional journey...and they don't want the whole journey to be the same.

Imagine yourself on a train ride where all you see the whole time is desert sand. You'd find that view interesting for about 10 minutes tops. Then you'd sit back and look for something interesting to read. A singer with a limited range knows in his gut that he only has one short bus tour for his audience and all the houses look the same. This makes him insecure so he may even try to "leap" for a high note by singing a song that's out of his range. He saw some superstar do it and it looked so easy. Yes, there is something worse that not having high notes in your performance...it's having high notes that you just can't do well.

Here are a few of my own "high note guidelines":

1. Don't EVER sing a high note that you haven't done successfully in rehearsal at least 20 times.

2. Don't set your entire concert in your extreme upper range. For an audience, this is the equivalent of listening to a dentist drill for an hour.

3. Don't fill your entire set with a ton of songs with climactic high notes. Remember, if you take your people to a peak, they feel its impact. If you take them to 8 more identical peaks, they lose the ability to feel it or respond...and eventually will resent you.

4. Realize that a good strong high note in your "mix voice" (see the Singing Success program for developing this) is a DIFFERENT experience for your audience than the same high note in FALSETTO. Both experiences are useful, but one says "power" and the other says "vulnerable." Use them appropriately.

5. It should be easy, but you can feel free to make it look hard. This is a performance choice you have to make. If you watch Andre' Bocelli, you'll get the feeling that he puts about as much effort into hitting his high notes as he does drinking a glass of champagne.

If you've had us help you find your high notes, they will indeed be easy. But if you're singing a popular style, especially rock, you'll want to give your audience the picture of strong emotion to go with that high note...just so they're not disappointed. So try to make it look hard.

If you are trying to perfect your upper register, but have never hade any formal training then this could be very difficult, and could cause serious damage to your vocal cords. I would suggest that you get some vocal training before trying to master super high notes. Without a good foundation for singing, developing your upper register is
not recommended. If you have never had any previous vocal training I suggest that you start by getting the
Singing Success Course, or some other singing program, and master it.

If you have already developed a good foundation for singing, and would like to learn how to sing super high note with ease, then I suggest that you check out the Top 7 Secrets to the Super-High Mix Voice.
