Bamboo tones are written like regular notes with different fingerings. Mostly the alternative fingerings are written above or below the note like this:
Piccolo - alto flute - bass flute
This technique can be used on all flutes.
This technique is easy to realize as a seperate technique. It becomes more difficult if alternated with regular sound very quickly. Still for advanced and professional players it will be easy to perform. Always make sure the fingerings are added in the score or in the appendix, because most fingerings are not common to all flute players.
