About this source

What it is

The Great Book of Music is an Arabic treatise written by al-Farabi, a 10th-century philosopher. It is divided into two treatises, the first covering the theory of sound and musical intervals, the second applying this theory to instruments used in his time.

Why it matters

The work shows al-Farabi following the Aristotelian tradition of splitting knowledge into theory and practice. It reveals him not just as a philosopher but as someone deeply engaged with the practical musical culture of his era, including the design of instruments like the shahrud.

Look closer

  • What does the detailed drawing of the shahrud tell you about how instruments were studied and recorded?
  • Why might a philosopher also want to understand music scientifically?
  • What parts of the original work are missing, and what does that tell us about how old texts survive?
