Abstract:

Ibn al-Munajjim lived in Abbasid Era in which music became a branch of science inIslamic Civilization. He wrote two valuable books on the theories of music. He came from“Müneccimoğulları family” known by its affinity to palace, and he was also an authority inArabic-Persian sciences. His teacher Ishâq al-MawsılÄ« was considered as the founder of thetheories of music in Islamic world; but his Works didn't reach us. And this increased thevalue of al-Munajjim's work, because his Risâla fi'l-MûsÄ«qâ gives detailed and importantinformations about the theories of music of that period. In researches on history of musicdone in western and Arab world Ibn al-Munajjim's Risâla was mistakenly mixed up by hiswork Kitâbu'n-Nagam. In this study we tried to connect this misunderstanding and weexamined Ibn al-Munajjim's –and consequently his teacher Ishaq's- theories of music. Wealso tried to give some informations about the life of Ibn al-Munajjim.
