Dobro Fills With B Half Whole Diminished

B Half Whole Diminished runs 8 notes to the octave. Below it is laid onto this chair's GBDGBD neck with every B marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.

Tense, symmetrical, and slightly sinister — alternating half and whole steps pack in the b9, #9, #11, and 13, so it sounds like a dominant chord stretched to breaking point. Edgy, jazzy, and restless.

Heard in: Jazz lines over 13b9 dominant chords, fusion, film-noir and horror scoring — the sound of a V chord that refuses to settle.

The dobro slides into notes rather than fretting them cleanly, so a scale here is a target list for the bar more than a set of stops — the slide finds the pitch, the scale says which pitch to find.

Play it slowly against the audio until the shape stops being a shape, then take it to a song in B and let the melody pick its own notes out of it.
