Fingerings for G, A, and B on the flute
Question: I just started learning how to play the flute. When I play G, A and B, I am supposed to press the E flat key down with my right pinky. But it makes no difference if I don't. Then why should I press it down?
Answer: That's a good question and one that is asked frequently.
The key system of the flute has evolved over the centuries to what it is now. I agree that this particular key often makes no difference if it is pressed down (which opens the key actually) or not. It may just be a hold-over from the key system of older flutes.
Professional flutists with an extremely acute ear will hear even the most minute differences of tone quality and pitch. For them the open or closed E flat key definitely makes a difference.
From a practical standpoint, having the right pinky pressed down helps to balance the flute as you hold it.
Bottom line? Press the key down, even if it doesn't make a difference in tone or pitch. It makes it easier to hold the flute, if nothing else. Eventually you'll be glad you learned the correct fingerings.
