Ionians

Ionians are an intelligent species native to Ionia, in the Ionian system. The name of their planet in their form of communication is a frequency of 441Hz, followed by 219Hz, 879Hz, 330Hz, and 219Hz.

Language and Anatomy
Due to Ionian's unique anatomy, they communicate through frequencies. Their gaseous blood and perfect control over their blood pressure allows them to create chords and melodies with their bodies that they use to communicate.

Innovation
Ionians revolutionized acoustics on planets such as Terra, Dembofathers, and Gra'am Bihitu. Their underground cities, largely designed around acoustics, acted as inspiration for many 22nd century ampitheatres on other planets. They are also credited with the invention of translator pedals, which translate audio communication input to audio communication output in another language through a speaker. It is structured similarly to a Terran talkbox pedal.
