D Locrian — Lap Steel
Every note of D Locrian 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 Locrian is 7 notes to the octave (modes 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.
The most dissonant, unstable mode — the tonic chord is diminished (b5), making a true Locrian tonal center rare. Used for color and passing harmony.
Heard in: Metal riffs, jazz (half-diminished ø7 chords in ii°7 – V – i), horror and tension film scores.
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.
