D# Locrian in Open A — Notes and Intervals
The D# Locrian scale is the seventh and most unstable mode of the major scale. On Guitar, the notes are D#, E, F#, G#, A, B, C#. It sounds highly dissonant and unresolved, as its home chord is a diminished triad. While rare as a primary key, it is a crucial technical tool for jazz musicians improvising over half-diminished chords in tension-heavy passages. The diatonic chords of D# Locrian are D#m7b5, EMaj7, F#m7, G#m7, AMaj7, B7, C#m7. Commonly used in Jazz, Metal, Experimental, Avant-Garde. Notable players include John Coltrane, Meshuggah, Dream Theater. Use over m7b5 (half-diminished) chords. Essential for jazz ii-V-i in minor keys where the ii chord is half-diminished.

About Open A Tuning
Open A tuning (E-A-E-A-C#-E) produces an A major chord when strummed open. It is structurally identical to Open G tuned up one whole step, delivering a brighter, more tense sound that works particularly well for slide guitar centered on the key of A.
Jimmy Page used Open A with a slide on Led Zeppelin's 'In My Time of Dying' from Physical Graffiti (1975). Rory Gallagher also employed Open A for his raw, energetic slide work. Many players achieve Open A by simply placing a capo at the 2nd fret in Open G tuning, which is why dedicated Open A usage is less commonly discussed. However, without a capo, Open A gives direct access to the open A string resonance and a different feel under the fingers due to the higher tension.
Notable artists: Jimmy Page, Rory Gallagher, Delta blues players
Best for: Slide guitar in the key of A, blues playing, and situations where you need the brightness of Open G tuned up without a capo
Musical Character
The only mode with a diminished 5th (b5) from the root, making its home chord a diminished triad. This instability means Locrian is almost never used as a key center — it is a tool for tension.
