Abu Nasr al-Farabi

Overview

Biography

Abu Nasr Muhammad al-Farabi (c. 872–950) — known in the West as Alpharabius — was a medieval Islamic philosopher, music theorist, mathematician, and cosmologist, regarded as one of the greatest scholars of the early Islamic Golden Age. Born in Farab (in modern Kazakhstan or Turkmenistan) of Turkic origin, he spent most of his productive life in Baghdad and later at the court of the Hamdanid ruler Sayf al-Dawla in Aleppo, where he died.

Al-Farabi earned the honorific "Second Teacher" (al-Mu'allim al-Thani) — Aristotle being the first — for his comprehensive commentaries on and extensions of Aristotelian logic, metaphysics, and political philosophy. His musical contributions are equally foundational: his Kitab al-Musiqa al-Kabir (Grand Book of Music) is the most comprehensive treatise on music theory produced in the medieval Islamic world. In it, he systematised the maqam scale system, described the acoustical properties of musical instruments, theorised the relationships between intervals, and laid out the principles of rhythm and meter in Islamic music.

Al-Farabi was himself a skilled practitioner: medieval accounts credit him with playing the oud with extraordinary skill and inventing the qanun (zither). His theoretical framework — linking music to mathematics, natural philosophy, and the human soul — was enormously influential on subsequent Islamic music theory and, through Latin translations, on medieval European musical thought. His work on the classification of musical modes directly influenced the systematisation of the maqam tradition that remains central to Arabic, Turkish, and Persian classical music.
