The G keys of a flute can be made inline or offset. There is no difference in the tone produced with inline or offset G keys, it is simply a matter of comfort and preference. Inline G keys are in a straight line with the rest of the keys on the flute and are all mounted on the same rod.
Offset G keys are offset slightly from the rest of the keys and are mounted on separate posts. A growing number of flutists prefer the comfort and hand position on the offset G flute. Azumi flutes are available with your choice of offset or inline G keys.
