The elbow is still up in the air and the head needs to be tilted and the neck twisted. Dr. Norris opened up the angle thirty more degree. Having the flute body slope down and the mouthpiece horizontal resulted in a straight neck and relaxed right arm. Head and neck remain centered and facing forward. Left wrist and first finger are no longer bent at extreme angles.
Arms are closer to center.
The 30 degree angle also balances like a straight flute with the 3 point balance between lip, left hand index finger and right hand thumb. My 30 degree angled headjoint has some modifications. I bought a silver plated model from Emerson Musical Instruments, but felt that it was not responsive enough for me. Chris McKenna replaced the lip plate and riser with those made of sterling silver and put a professional cut on the embouchure.
