The pan flute is named after Pan, the Greek god of nature and shepherds often depicted with such an instrument. Pan and Daphnis – 1st century BC Roman replica of 2nd century BC Greek original In Greek mythology, Syrinx (Σύριγξ) was a forest Nymph. In her attempt to escape the affection of god Pan (a creature half he-goat and half man), she was transformed in water-reed or calamos (cane-reed). Then, Pan cut several reeds, he placed them in parallel one next to the other, bound them together and made a melodic musical instrument. Ancient Greeks called this instrument Syrinx, in honour of the Muse, and Pandean, or Pan-pipes and Pan-flute, after Pan. The Syrinx, a predominantly pastoral instrument for the Greeks, was adopted by the Etruscans who played it at their festivals and banquets; the Etruscans called it fistula. The Romans adopted the Syrinx from the Greeks and the Etruscans, and they too played it at their banquets, festivals, as well as in religious and funeral processions. The pan flute is played by blowing horizontally across an open end against the sharp inner edge of the pipes. Each pipe is tuned to a keynote, called the fundamental frequency. By overblowing, that is, increasing the pressure of breath and tension of lips, odd harmonics (notes whose frequencies are odd-number multiples of the fundamental), near a 12th in cylindrical tubes, may also be produced. The Romanian pan flute has the pipes arranged in a curved array, enabling the player to easily reach all the notes by simply swiveling the head. These instruments can also play all the sharps and flats, with a special technique of both tilting the pipes and jaw movement, thus reducing the size of the pipe's opening and producing a change in pitch. An advanced player can play any scale and in any key. There are two styles of vibrato possible, hand vibrato and breath vibrato. In hand vibrato, the player applies a gentle motion to one end of the pan flute (usually the high end) in much the same way as the violin vibrato is achieved by rocking the hand from the wrist. Breath vibrato is the same technique used by players of the flute and other woodwinds by use of the player's diaphragm.
