Hazrat Inayat Khan (1882 – 1927) was an exemplar of Universal Sufism and founder of the "Sufi Order in the West" in 1914 in London. Later, in 1923, the Sufi Order of the London period was dissolved into a new organization called the "International Sufi Movement". He initially came to the West as a representative of classical Indian music, having received the title Tansen from the Nizam of Hyderabad but soon turned to the introduction and transmission of Sufi thought and practice. "Music" is a compilation of lectures given by Hazrat Inayat Khan. It conveys an insight into the deep knowledge of Indian mysticism and music in a very simple language. His teachings on sound present a vision of the harmony which underlies and infuses every aspect of life; science of breath, law of rhythm, the creative process, healing power and psychological influence of music.
