The sipsi (pronounced [sip'si]) is a Turkish woodwind instrument. It is a clarinet-like, single-reed instrument used mainly in folk music. The word "sipsi" is possibly onomatopoeic. The Redhouse Turkish-English dictionary defines "sipsi" as "1. prov. whistle; boatswain's pipe. 2. reed (of a clarinet)." The Turkish Language Society lists "sipsi" as "1. A?aç dallar?ndan yap?lan düdük. [a whistle/flute made from the branch of a tree.] 2. Gemici düdü?ü. [Sailor's whistle/pipe.] 3. Zurnan?n dudaklara gelen kam bölümü. [The reed section that fits into the opening (lips) of a zurna.]" No link is made in either dictionary to any other Turkish word. The sipsi, however, is an instrument native to the Aegean region of Turkey, which has a millennia-old history of sea-faring, hence the reasonable association with the bosun's pipe.
The sipsi can be made of bone, wood, or reed, though the reed variant is most common. Its size varies from region to region, but it generally contains five finger holes in the front, and one finger hole in the back.
The sipsi is one of many reed instruments in Turkey used to play lead melodies in instrumental folk music. It is generally played in the Western part  in the Aegean Region of Turkey. Most folk tunes played in this area with the sipsi are in 9/8 time.
The timbre of the sipsi is similar to that of the Irish bagpipe, and players of the sipsi also employ the circular breathing method, in which air is breathed through the nose while it is being pumped out of stored air in the cheeks. This breathing method is used to form an uninterrupted sound.
To tune the sipsi, one must wrap a thread around the bottom of the reed, which is placed into the main body of the instrument. Adjusting the reed with the string is the way to tune. The instrument's range is greater than its six finger holes would suggest, the upper registers can be attained by particular approach to breathing.
