What is a Split E Mechanism? 

The Split E Mechanism on a flute is a special key modification that makes producing a clear and stable upper-register E easier! 

How It Works

On a standard flute, pressing the G key typically closes the G key and the neighboring key to its right. The Split E Mechanism, however, adds an additional rod that connects the E key to the second G key, allowing for independent movement and improved control over high E. This design enables the second key to close on its own when playing high E, a note that would normally remain open on a standard flute.

This modification improves the flute’s response, making E6 more secure and easier to play.

How do I know if I need one?

Not every flute needs a Split E Mechanism. On certain flutes, the high E speaks easily, but having it can still be a great advantage! The Split E Mechanism will help intermediate to advanced players who struggle with high E, and flutists looking for a more balanced tone and easier high-note control.

Are there any drawbacks?

When choosing a flute with a Split E Mechanism, it's important to consider two factors: the extra weight from the added rod and the higher cost of the addition.

What if my flute doesn’t have it? Can I add it after?

Unfortunately, you cannot add a Split E Mechanism on a finished flute. Instead, some flutists opt to add a G Disk (or G Donut). A G Disk is a small metal insert placed inside the G tone hole of a flute. It is commonly used in flutes with an open-hole (French) G key to improve the response of the high E note.
