D Persian — Lap Steel
Every note of D Persian as a bar position on the lap steel's six strings in C6 — the root ringed each time it recurs, and a button that plays the run.
D Persian is 7 notes to the octave (world family), drawn here across the lap steel's six strings in C6 with every D marked, so home stays visible from anywhere in the pattern.
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.
On a lap steel a scale is played by moving the bar: every note on a string sits a fret apart, and the tuning decides which neighbouring string holds the next one without a slide. These maps light every root so the bar always knows where home is.
Work it in one position before you work it up the neck. A bar that lands a hair short of the marker sounds flat on every string it covers, and the ear hears that long before the run is fast.
