These two links are for use by Miller Middle School students and teachers only. Those from other schools who wish to use them should purchase the Embouchure Project from Teachers Pay Teachers.
After practicing the embouchure many times while checking in the mirror for correct position and practicing playing longer and longer tones, you are ready to check for correct pitch.
You should be able to produce a concert A with your headjoint only (stopped or open). Use a tuner to check your the pitch of a note (if you don't know how to use a tuner, see instructions below). You can also play an A on the piano to check your pitch by ear.
If your headjoint note is A, you are on your way to producing a beautiful, correct ("characteristic") tone on flute. Instrumentalists must produce a consistent, characteristic tone in order to play in tune.
If you are not getting the correct pitch, check the following:
The flute tuning note is A above the staff. Play F G A Bb slurred, then go to A and tune.
Play your tuning note towards the the tuner. If the needle stays towards the right, your note is sharp, and you need to pull the headjoint out to lower the pitch. Start off by pulling it out at least 1/2 inch. If it stays towards the left, your note is flat, and you need to push the headjoint in to raise the pitch.
Keep moving the headjoint in or out and retuning until the needle stays in the middle, which means your note is in tune.
The goal is to get the needle to stay in the middle as you hold out the tuned note. Once you can play the note in tune with the tuner, see how long you can hold the tuned note. Play "freeze the needle" - hold the note steady and in tune.
Keep in mind that even though you will first use these notes to tune, other notes on your instrument may not be in tune. It is the nature of instruments. The longer you play your instrument, and the better, more characteristic tone you can produce, the more you will be able to play all notes in tune on your instrument.
As you progress on flute, you will also learn to improve your intonation, which means to adjust your instrument and/or embouchure slightly while playing (without pushing in or pulling out). Adjustments for intonation help improve the pitch of different notes in action. You use your ear and make adjustments while playing.
In a nutshell...
The longer the pipe, the lower the pitch. If your pitch is sharp (high), you need to make it flatter (lower).
The shorter the pipe, the higher the pitch. If your pitch is flat (low), you need to make it sharper (higher).
