The Lute ----- Al'ud, Oud

The Moors brought the oud to Spain. The tanbur had taken another line of development in the Arabian countries, changing in its proportions and remaining fretless.
The Europeans added frets to the oud and called it a "lute" - this derives from the Arabic "Al'ud" (literally "the wood"), via the Spanish name "laud".
A lute or oud is defined as a "short-necked instrument with many strings, a large pear-shaped body with highly vaulted back, and an elaborate, sharply angled peghead".
