Wow.. the angle of your neck, what does your teacher say? I am torn though... I have only ever seen one other pianist ever who played with almost that exact neck angle--your mannerisms and the way your face shows such expression.. It's really kind of spooky... even your sound...
he was, in the opinion of many, the greatest jazz pianist who ever lived. His name was Bill Evans. I searched through a few pages of video thumbnails before I found a picture that showed this.. and wouldn't you know it... the recording--is a tune called Peri's Scope it was the first Bill Evans tune I ever learned.
given my odd dream the other night... please check this guy out. There are tons of videos of him performing live..
in spite of this... there seems to be a lot of tension in your neck.. I love your playing AJ--but I have bad neck and back problems from poor posture at the piano. Please don't ignore the pain if you feel it in your back, neck, elbows, wrists or shoulders or if you start to get that tingly feeling.
