Farabi classified the sciences. Before him, the sciences were collected in two parts called trivium (triplet) and huatrivium (quadruplet). Nahiv, logic, declaration were included in the triplet sciences; mathematics, geometry, music and astronomy were included in the quadrilateral sciences. Farabi, on the other hand, divided the sciences into three; physics, mathematics and metaphysical sciences. His method was adopted by European scholars only in the thirteenth century. Farabi made the first logical explanation of the sound phenomenon, which consists of air vibrations. He determined that the vibrations decrease and multiply according to the wave length by conducting experiments. With this discovery, he also found the bases necessary for the construction of musical instruments. At the same time, Farabi, who is working in the field of medicine, has written works about various medicines on this subject. He was considered a philosopher who came after Aristotle.
