Building an Oud — The Fretless Arabic Lute

The oud is the deep-bowled short-necked lute of Arabic and Turkish music. Unlike a guitar or bağlama it has NO frets, so a player can slide the fingers to any pitch — including the microtones between the Western notes.

Build a deep, rounded bowl body from many thin wooden staves (ribs) glued edge to edge over a mould. The big bowl gives the oud its warm, resonant voice.

Glue a thin flat soundboard over the bowl and cut one or more decorative sound-holes (rosettes) in it.

Fit a short, SMOOTH neck — no frets at all — ending in a pegbox that bends sharply back from the neck, the oud's signature shape.

Fit the pegs and string it with paired courses — bright strings for the high courses and thicker wound strings for the low ones. An oud usually has eleven strings in six courses.

Tune the six courses low to high. Doubling most strings in a course makes the sound fuller and richer.

Pluck the strings with a long thin plectrum (the risha), pressing the strings onto the bare, fretless neck with your other hand.

Because there are no frets, slide a finger up or down the smooth neck to glide between notes and land exactly on the in-between pitches that make an Arabic maqam.

A plucked string sounds higher the shorter its vibrating length, and pressing it against the neck is how you shorten it. A FRET is a fixed ridge that stops the string at one exact spot every time, which makes it easy to hit set notes accurately but locks you to those notes. The oud does the opposite on purpose: its neck is left perfectly smooth, so the string is stopped only by the soft pad of your finger, wherever you place it. That means you can land on any pitch at all — including the neutral, in-between microtones that Arabic and Turkish maqam music lives on, which fall in the cracks a fretted guitar can never reach — and slide smoothly from one to the next, bending and ornamenting notes like a singing voice. The price is that intonation is all in the player's ear and fingers, with no frets to guide them. The deep staved bowl and thin soundboard amplify the strings as in any lute, and the sharply back-bent pegbox keeps the short neck balanced. The oud is the direct ancestor of the European LUTE (the very word 'lute' comes from the Arabic al-ʿūd), and a cousin of the fretted bağlama and, distantly, the guitar — the whole family of plucked, soundbox strings whose oldest Youblob ancestor is the lyre.
