Thanks to countless TV ads hawking collections of his music, Zamfir is almost universally recognized as the "Master of the Pan Flute." While that title may be cause for smirking in some quarters -- whether because of its overexposure or a general distaste for easy listening music -- it's true that Gheorghe Zamfir was single-handedly responsible for popularizing an ancient, traditional Eastern European instrument that was in danger of dying out for lack of interest. Made of bamboo, reeds, or wood, the pan flute (also known as the pan pipes or the nai) consists of a series of tubes, each of which sounds one individual note, and are fastened together side by side. It produces an ethereal, haunting sound, and since its construction makes the execution of up-tempo passages nearly impossible, it's ideal for the sort of slow, tranquil mood music that constituted Zamfir's stock in trade. At first focusing on Romanian folk melodies, classical material, and original compositions, Zamfir's popularity in Europe and America led him to cover pop songs, soundtrack themes, and the like, all supported by soft, lush orchestral arrangements.
