The flute in combination with the amaroch pitch language to communicate across long distances. This is possible due to the extremely high pitched sound of the flute. Most of the notes played by the flute are only audible to the Eledhrim
(and other animals that can hear that band of sounds). The lowest register of the flute is barely audible by Anthros
under the age of 20 and it is an extremely irritating sound described as " the most horrible mosquito noise you ever heard" and can cause dizziness and in some cases nausea to the point of vomiting.
