About A Dim 9 in Drop D
The A Dim 9 chord contains the notes A, C, D#, F#, B. In Drop D tuning (strings: D–A–D–G–B–E), the chord shapes differ from standard tuning because the open string pitches change. Drop D lowers the low E string to D, making power chords and D-root chords easier to play. Diagrams above show all playable shapes in this tuning.
