My Flute wont play some notes?

I cant play any notes that I have to press with my fingers on my left hand like d, e, e flat or f. During class it worked fine, but after school during practice it stopped. What could be the cause of this and how can I fix it?

Your flute has a leak. Take it to a repair technician or a music store that has a repair department.

Leaks are a fairly common problem with flutes. They happen when one of the keys is not closing entirely, usually one of the keys that are not operated directly by a finger. In your case it's probably one of the keys between the left hand keys and right hand keys.

There are several things that can cause a leak: a broken or unhooked spring, a worn or damaged pad or a key that has come out of adjustment in relation to another key. Any of these problems are easily fixed, but they require special equipment and training that only a repair technician has. Fortunately these simple repairs are generally inexpensive.

You need to take it to the shop so they can fix it. Maybe your pads fell out and you need to replace them. It is harder to play without them.

Loose fitting pad over holes?

Lots of air?
