Qeichak (Gheichak); Persian Musical Instrument
The qeichak belongs to the family of arched chordophones. This instrument in various parts of Iran is called by names like ghazhak, ghazak, ghachak, ghajh, qichak (Sistān) and sorud or soruz (Baluchistān). The qeichak is one of the most important instruments of the Sistān and Baluchistān region but is also found in some areas of Hormozgān and Kermān.
This instrument consists of a two-part harmonic case whose opening in the lower part is covered with leather while the upper part is open. Its handle is short and ends in a tuning box and a head. It has two rows of strings, the first row is made up of the main strings whose number in the Balichistān qeichak is equal to 4 while in that of the Sistān it is equal to 3 and above them an arc is stretched. The second row are the secondary strings that are 7 in the qeichak of Sistān and Baluchistān and an arc is stretched over them. The sound is emitted by the vibration of the main strings.
The qeichak of the Sistān is narrower and taller than that of the Baluchistān and the number of the strings is also lower; moreover his executive techniques are simpler. This instrument, which is played in most of the Baluchi musical genres, is used only in weddings and parties in the Sistān.
