Oud

The oud ( OOD; Arabic: عُود, romanized: ʿūd, pronounced [ʕuːd]) is a Middle Eastern short-neck lute-type, pear-shaped, fretless stringed instrument (a chordophone in the Hornbostel–Sachs classification of instruments), usually with 11 strings grouped in six courses, but some models have five or seven courses, with 10 or 13 strings respectively. The oud is similar to other types of lute, and to Western lutes which developed out of the Medieval Islamic oud. Similar instruments have been used in the Middle East, some predating Islam, such as the barbat from Persia.

And its depth seven and a half fingers. And the measurement of the width of the bridge with the remainder behind: six fingers. Remains the length of the strings: thirty fingers and on these strings take place the division and the partition, because it is the sounding [or "the speaking"] length. This is why the width must be [of] fifteen fingers as...
