D Persian — Tenor Guitar

D Persian is 7 notes per octave (world family), drawn here as position boxes on the Tenor Guitar's CGDA grid with the root flagged in each — learn one box deeply, then let the overlaps carry you into the next.

Intensely exotic — two half-step clusters (b2 against the root, b5 against the 4) and a raised 7th make it the most dramatic of the world scales. Mysterious, ornate, and tense.

Heard in: Persian and Middle-Eastern-flavored melodies, film scoring for desert and ancient settings, and exotic metal and progressive-rock riffs.

Fifths spread each scale wider per string than a standard guitar — fewer notes per position, longer reaches, and patterns that repeat cleanly across every string pair.

Play each box top to bottom until the roots feel like home base, then practice crossing between boxes mid-phrase — neck freedom is exactly that crossing, nothing more.
