Aeolian sounds are colored air sounds with no normal flute tone. This Air stream across the embouchure produces an airy pitch resonance in the first octave only, low B- middle D# (up to middle F# by using the trill keys). The sound color can be changed by changing the shape of the inside of the mouth—distance between the teeth and/or by using different vowel shapes.
To produce Aeolian Sounds use a "duck-face" embouchure, allowing the air to flow over the top of the embouchure hole. In order to avoid normal flute tone, you can bite your teeth together.
The flute is particularly suited to adding more or less tone to the colored air sound with seamless transitions between pure air and normal flute tone.
Despite the fact that Aeolian Sounds are only possible in the lowest octave, higher registers can be played with a similar color, mixing the normal flute tone resonance with an unfocused air stream. However, this is not true Aeolian Sound.
Aeolian Sounds can be colored with different vowels or phonemes. You can choose one that would enhance the gesture's effectiveness, such as an [sh] phoneme in a wind-like gesture.
