Auoloi
The auloi was a twin double reed instrument (like the modern oboe), you could change the pitch with your fingers and by changing the distance between the reeds in his mouth.
The auloi was important for the culture, but could not be used as such by the phiolosophers for determining pitch, since the pitch could be changed by how you held the double reed in your mouth.
