This thesis offers results and exploration to fill in this distinct gap in the literature. As such, it tries to find eastern-western musical contact and patterns of integration.This thesis explores mutual interest and assimilation of music between the Iberian Peninsula and China, representing the two farthest civilizations on the Eurasian continent, in both early history and the recent few decades. These are both important periods of time for study.The first period that this thesis examines is around 600-900 CE. This is prominent because it is the period of first sustained and well-documented cultural contact between the civilizations of these two areas. This is across the period of the Silk Road, when trade routes stretched from the eastern coast of China to Mediterranean Europe. At this time, Spain was under various reigns including the Muslim era under the control of the Moorish Muslims of North Africa. Meanwhile, the area of China was under the control of the Sui and Tang Dynasties. This period also has the earliest detailed historical source material dedicated to music.The second period that this thesis examines for comparison is the past few decades from 1970s to present day.
