Dissecting the B Dim Chord: Notes and Construction
The B diminished chord is comprised of three notes:
- B (Root)
- D (Minor Third)
- F (Diminished Fifth)
These notes, when played together, create the characteristic diminished sound, often described as tense, unstable, or even melancholic. The formula for constructing any diminished chord follows a specific interval pattern from the root:
| Interval | Semitones from Root |
|---|---|
| Root (1) | 0 |
| Minor Third (b3) | 3 |
| Diminished Fifth (b5) | 6 |
This consistent interval structure applies to all diminished chords, making it easier to understand and apply the concept to other roots.

Scales for Soloing Over the B Dim Chord
Due to its inherent tension and dissonant nature, choosing the right scale to play over a B diminished chord is crucial. The Locrian scale is a theoretical match because it contains both the b3 and b5 intervals found in the diminished chord. However, its overall sound can be quite dissonant and might not always be musically desirable in all contexts.
More practical and musically pleasing scales to explore over a B diminished chord include:
- B Minor Blues Scale: The minor blues scale works surprisingly well, with the b5 acting as the characteristic “blue note,” further emphasizing the diminished quality.
- B Dorian #4 Scale: This mode adds a raised 4th degree, creating a unique flavor that complements the diminished chord.
- B Whole Tone Scale: The whole tone scale, with its symmetrical structure, creates a dreamy and ambiguous sound that can work effectively over diminished chords.
