Composers use different ways to indicate that you should play wind tones. Here are some possibilities:
Some composers use stripes under or over the note. No traditional flute sound should be used, only air.
Some composers use a triangle as a note head to indicate that you should play a wind tone without traditional flute sound.
If a combination between a regular note head and a triangel is written, one should combine traditional sound with a wind tone.
Most composers include a page of instructions with their piece. Sometimes composers simply write into the score what they want to hear.
Piccolo - alto flute - bass flute
This technique can be used on all flutes.
This technique is easy to achieve on the flute. It becomes a bit more difficult if it is quickly alternated with traditional sounds or other techniques.
Wind tones without a combination of traditional sound only work in the first octave. The second octave sounds the same as the first octave.
Studying wind tones on the flute is useful for:
– Flexible embouchure
– Improving sound quality
Example of wind sounds combined with traditional flute sound. I’m playing Xi by Karlheinz Stockhausen.
This is an example of a Flute Colors arrangement including windtones without traditional flute sound:
