Binjoo Instrument: Binjo is exported to Iran from Pakistan about fifty years ago and is one of the Baluchi instruments. Binjo is one of the string-percussion instruments and is classified as stringed instrument which used mallet for playing . It is played without the intervention of the fingers and is made with the help of metal buttons or knobs and blades that touch the curtains and chords and thrilled them. History: About 80 or 100 years ago, it came to Balochistan as a toy from Japan. Then, at the initiative of the young Balochi, it became a local instrument. Therefore, it is not considered a native Baluchi instrument. Due to its proximity to the climate of India, the symphony of this instrument are influenced by Indian music. Structure and characterization: Body: The Bingo includes a long, elongated geometric reverberation box with a wooden screen on it. The depth of the reverberation box is low and the vault is installed on a wooden plate. The lower part is in the shape of a rectangular square with arched sides. The arches are symmetrical in the middle of the sides of the reverberation body, with a perforation in the middle. The lower part of the body is smooth and the upper part is rectangular and wide. On the part of the body, there is a large and smooth wooden board, which the lower ends comes up with the upper part of the box and is arched. Next to it are the button keys. The upper part also is ended up with screen of earphones in a cracks shape. earphones screen: They are solid and are in the form of nails or rods. Vault: It is located at the end of the body. cords: The Binjo has 6 cords that connect to 6 earphones. The two main chords, the third and fourth chords, pass from the two main vault. Two other vaults are related to the first and sixth lateral chords, and the second and fifth chords don’t connect to any vault. So, Binjo has 3 vaults. Interface curtains only come in contact with the third and fourth chords, and the rest of the chords are free. Of the 6 chords, two are melodic and the rest are vocal. The wires pass under a large, flat wooden board on the body of the instrument, and after passing through the vault, fasten to the tailpiece at the end of the body. The tuner is made of iron keys. On the left side of the Benjo is the holder handle.  The relatively long stick is placed on a wooden plate as a base for storing curtains and vaults. This base is a bunch of handles and the curtains are placed on it in the form of a thin metal blade. Benjo is made from local Pakistani wood, such as hadd or baber. Bingo has 30 buttons, 17 of which are large and the rest smaller. The position of the buttons under the player's left hand is almost similar to that of a piano keyboard. While playing, the musician presses these keys with his left hand. Benjo Curtain: Curtains are mostly used to create chromatic sounds of the tambourine, which due to the inaccuracy in the installation or manipulation of the musician, the sound does not match the chromatic step of the tambourine. Performance: Binjoo’s mallet is made of soft plastic, which is in contact with almost all chords when playing. However, due to its special structure, it does not have a special executive technique for the right hand and is mostly in the form of reciprocating, small and Dorrab. All five fingers of the left hand are used to hold the thumbs and buttons. Administration: It is used in the performance of happy Balochi songs called "Saut" and is played alongside common instruments in Balochistan.  musicians: Mohammad Omar Sepahi Mohammad Ali Delnavaz builders Mohammad Omar Sepahi Mohammad ali Delnavaz
