G/A trill key

Two extra small tone holes are positioned on the body.  One is to the left of the G# key the other is to the left of the thumb key.  The touch piece is usually next to the first trill key and when both trill keys are used together an easy G/A trill is achieved.  It is usually found on a flute with E mechanism as the addition of E mechanism makes a third octave G/A trill difficult (see also C# trill key).  The G/A trill is less often found than the C# trill mechanism.
