What a great feeling, the first time (that being this thread) that anyone has given me positive comments on my high notes. To be given some assurance from outside sources that I'm on the right path just fills me with so much desire to sing even harder, it's a feeling I'm sure you are all well aware of. Thank you Jens for the comments and thank you all for your comments. Time to get singing and really get gung ho with this method that I'm using to do it!
Last week I quite literally for the life of me could not even approach a Bb4, not in the 2 or so years I've been singing on and off. I could never imagine how I would be able to do it. A couple simple conscious modifications to my technique, and now it's totally easy relative to what it was before.
