highlights on al-Kindi and on his music theory
Al-Kindi was the first great theoretician of music in the Arab-Islamic world. He is known to have written fifteen treatises on music theory, but only five have survived. He added a fifth string to the 'ud.[51] His works included discussions on the therapeutic value of music[52] and what he regarded as "cosmological connections" of music.[53]
