The Mey and Duduk are two closely related instruments of the double reed family. Perhaps best known in America are the duduk performances on the soundtrack to "The Last Temptation of Christ", where the mournful and plaintive tone of the duduk is used to great effect.

The Mey is the Turkish name, Duduk the Armenian term, for an ancient woodwind instrument that also includes the Balaban of Central Asia and the Chinese Guan among its varieties. The essential feature is a short cylindrical tube with 7 or more fingerholes and one thumbhole coupled to a very large flattened grass reed, with some sort of adjustable "bridle" affixed to the reed. Even though it is sounded with what looks like an inordinately large zurna (sorna, mizmar, raita, suona, shenai, shawm, etc.) reed, inviting classification in the oboe family, the double reed in question behaves more like a clarinet, in that unlike the zurna and other early and folk oboes, the mey/duduk is capable of dynamic shadings from a whispered pianissimo to a full forte- although it is not capable of the blasting fortissimo of the folk oboes, allowing the mey/duduk to be used indoors in intimate situations. It also is a significant voice in the Armenian orchestra, carrying significant melodic material. Several sizes are found, tube lengths ranging from 6 or 7 inches to over 16 inches.

Again acting like the clarinet, the cylindrical tube and reed function as a tube closed at one end, and thus play an octave lower than one would expect for a short tube. Bora Ozkok referred to the Turkish mey as the "grandfather of the bassoon", although the clarinet is a better analog. Indeed Turkish clarinet style is heavily based on the older styles of mey playing.

The basic 7 hole + thumbhole fingering is also the same as that of the zurna family; that is, it produces roughly a major scale plus one note above, the range of a ninth. "Roughly" a major scale because it produces a natural scale, not a tempered one, although the lip can bend a note enough to play any interval, plus half-holing is also used to fill in the many shadings of pitch used in Oriental musical systems. On the rarer models with more than 7 fingerholes, the additional holes are located at the lower end of the tube.

It is difficult to give a definitve pitch of the various sizes of mey or duduk as the same instrument may play as much as a whole step apart with different reeds. One can only be precise about the pitch of a specific reed and tube combination.
