He is considered a master of traditional Mevlevi Sufi music and is one of the best-known players of the Turkish ney flute.

For several decades, he has researched the earliest roots of Ottoman music which he has also taught, performed and recorded.

In the seventies Erguner moved to Paris where, at the beginning of the eighties, he founded the Mevlana Institute devoted to the study and teaching of classical Sufi music.

Together with the Kudsi Erguner Ensemble he developed deep insights into the diversity of his culture: the group conveys both authentic, often improvised forms of expression of classical Ottoman performance culture as well as a comprehensive repertoire of modern and classical pieces that can be traced back to the 13th century.

In addition to his own recordings, Erguner has performed with Peter Gabriel (The Last Temptation of Christ soundtrack), William Orbit's band Bassomatic (Set the Controls for the Heart of the Bass), Jean Michel Jarre, Maurice Béjart, Peter Brook, George Aperghis, Didier Lockwood, Italian singer-songwriter Alice and Michel Portal.
