Oud Fingerboard Explorer — CFADGC

Nothing marks the oud fingerboard, so this reference places each selected pitch where twelve-tone tuning would put it on CFADGC.

An interactive note map of the Oud's fingerboard in CFADGC: tap a note to light it on every course, and watch the lattice this tuning builds — CFADGC — six courses whose outer pair both sound C, two octaves apart, with every adjacent pair rising.

Light a single pitch and count how many courses it lives on across the neck — with six courses tuned mostly in fourths, most pitches repeat more than once, which is exactly the kind of reach that makes a taqsim possible on an instrument with no chord to lean on.
