To a certain degree we may look for remnants of Byzantine or early (Greek-speaking, Orthodox Christian) near eastern music in the music of the Ottoman Court. Examples such as that of the eminent composer and theorist Prince Kantemir of Romania learning music from the Greek musician Angelos indicate the continuing participation of Greek-speaking people in court culture. However, the sources are too scarce to permit any well-founded stipulations about what cultural musical changes took place when and under which influences during the long histories of the Byzantine and the Ottoman empires. Hypotheses that Turkish (Ottoman) music was influenced by Byzantine music, or the other way around, remain highly speculative.[citation needed] It seems more logical to consider that these influences were probably more manifold, considering the breadth and length of duration of these empires and the great number of ethnicities and major or minor cultures that they encompassed or came in touch with at each stage of their development.
