Alright, so the high note in the last 10ish seconds of the video is one I can hit.
It's a F6, and I can go to F#6 almost G6.
I can hit the note, but I need to work on sustainability and the overall sound and vibrato. I've been working on it for a few days and am actually pretty proud of myself, and have noticed a lot of improvement!
Of course, this is going to take a lot longer than a few days, but hopefully in a few years I can get it just as good as the same girls who play Christine!
