In the 20th century, the mandolin was prominently used for bluegrass, classical, and jazz music. The mandolin family The few other members of the mandolin family are the mandola, mando-bass, octave mandolin, piccolo, mandocello, and cittern.

Unfortunately, most of which are historically inaccurate and, thus, impossible. The most common theory is that Amir Khusru invented the sitar around 1300 AD. This is a different Amir Khusru from the one stated above. The Amir Khusru of the 1300 AD was a popular personality and is an image for the Hindustani Sangeet. In the middle of the 1920 s, the tenor had 19 frets and was twenty-two to twenty-three inches long. The rarest type is the cello banjo. It has the same range as the mandocello and cello and is tuned one octave lower than the tenor banjo. Four-string banjos can be for choral accompaniment and single string tune playing.
