Hakham Bashi (Ottoman Turkish: حاخامباشی, Turkish: Hahambaşı) is the Turkish name for the Chief Rabbi of the nation's Jewish community. In Ottoman times it was also used for the chief rabbi of a particular region such as Syria or Iraq, though the Hakham Bashi of Constantinople was the considered head of the Jews of the Empire.

The institution of the Hakham Bashi was established by the Ottoman Sultan Mehmet II, as part of his policy of governing his exceedingly diverse subjects according to their own laws and authorities wherever possible. Religion was considered as primordial aspect of a communities 'national' identity, so the term Ethnarch has been applied to such religious leaders, especially the (Greek Orthodox) Ecumenical Patriarch of Constantinople (i.e. in the Sultan's imperial capital, renamed Istanbul in 1930 but replaced by Ankara as republican capital in 1923). As Islam was the official religion of both court and state, the Chief Mufti in Istanbul had a much higher status, even of cabinet rank.

The bansuri (Hindi: बांसुरी, Nepali: बाँसुरी, Marathi: बासरी, Assamese: বাঁহি, Bengali: বাঁশি) is a transverse flute of India made from a single hollow shaft of bamboo with six or seven finger holes. An ancient musical instrument associated with cowherds and the pastoral tradition, it is intimately linked to the love story of Krishna and Radha, and is depicted in Buddhist paintings from around 100 AD. The Bansuri is revered as Lord Krishna's divine instrument, and is often associated with Krishna's Rasa lila; mythological accounts tell of the tunes of Krishna's flute having a spellbinding and enthralling effect not only on the women of the Braj, but even on the animals of the region. The North Indian bansuri, typically about 14 inches in length, was traditionally used as a soprano instrument primarily for accompaniment in lighter compositions including film music. The bass variety (approximately 30", tonic E3 at A440Hz), pioneered by Pt. Pannalal Ghosh and elevated to heights of global renown by the brilliance of Pt. Hariprasad Chaurasia has now been indispensable in Hindustani Classical music for well over half a century. Bansuris range in size from less than 12" to nearly 40".
