Difficulty: Moderately Easy
Step1
Learn what type of wood your flute is made of. Flute-makers don't always agree on what type of wood produces what type of sound, but many traditional flutes are made of red cedar, spruce or fir. These are said to have a bright or crisp tone.
Step2
Check the inside of the flute, from the far end up to the windway. If there is any glue or debris inside, clean it out thoroughly. Use a small stick wrapped in cloth, or a fine sandpaper, to help clean out any materials you find.
Step3
Look at the size of the windway. If it is too large, your sound may be breathy and low. If it's narrower, you could get a higher pitch. Sand it to make it wider, or narrow it with carefully-applied glue or the addition of a thin metal piece.
Step4
Make sure the windway is clear, and open it if it's clogged. If it isn't clear, your breath can't get from the first air chamber to the main body of the flute.
Step5
Examine the block that sits atop the windway and sometimes has the windway carved into it. If it isn't attached securely, it can't properly direct the air flow into the sound chamber. It may also need to be cleaned.
Step6
Inspect the holes. They should all be the same size opening, and their edges should be smooth. Sand them if necessary. Make sure that your fingers can completely cover each hole.
Step7
Scrutinize the mouthpiece, and remove it if possible. Make sure that it's clean and smooth on the inside and outside.
