Oud is tuned C–F–A–D–G–C, with 12 frets to work with. Positions are computed for this tuning; traditional technique may use idiomatic voicings not shown here.

Each position shows the scale notes and their intervals from the root so you can connect the shape to its sound, hear it with audio playback, and practice it in any register. Movable patterns let you transpose the same fingering to other keys once it is learned.
