High E has always been considered a problem note on the flute. It is easily cracked and tends to be quite sharp, especially in forte passages. Ideally, the high E should be fingered with the G keys (ring finger on your left hand) split so that the bottom key (of the connected keys) is down and the other is up. The split E accomplishes this by dividing the normally connected G key structure so that it will work simultaneously for G yet independently for high E. The G "Donut" insert is a popular alternative to the split E Key. It can be installed as an option on a new flute and is also available for flutes after originally purchased.
1) Rapid slurs from high A to high E speak easily with no special fingerings.
2) Quick leaping passages from lower notes to high E and back present little or no problem as the high E speaks freely.
