Diminished Whole-Half: guitar scale formula, degrees and fretboard patterns

Scale formula

Formula: 1 2 b3 4 b5 #5 6 7. Classification: symmetric.

Description

Detailed explanation The whole-half diminished scale is an eight-note symmetric scale alternating whole-steps and half-steps — the version for a diminished 7th chord. The characteristic sound It's fully symmetric and built around the diminished chord. The sound is tense, anxious and full of suspense. Tonic and function The tonic is dim7. By symmetry one shape repeats every minor third, so there are only three different scales. Chords and use Over a diminished 7th chord (dim7), especially a passing one. Classical and jazz. Essence An eight-note symmetric scale over dim7. It starts with a whole-step.

Degree functions

• I — Symmetric root: Degree I serves as the reference point inside symmetry but does not create ordinary tonal stability.
• II — Whole-step lift: Degree II opens the ascending symmetric cell.
• bIII — Minor third: Degree bIII links the scale with diminished structures and dim7.
• IV — Support fourth: Degree IV gives intermediate support inside the symmetric pattern.
• bV — Flat fifth tension: Degree bV preserves diminished sharpness.
• #V — Sharp fifth color: Degree #V expands the vertical sonority and supports chromatic mobility.
• VI — Natural sixth color: Degree VI adds a bright shade inside overall instability.
• VII — Major seventh tension: Degree VII intensifies internal tension and instability of the scale.
