Bb Harmonic Minor Scale in 7-String Drop A Tuning

Bb Harmonic Minor Scale in 7-String Drop A Tuning shows the same bb harmonic minor scale pitch classes across 7 strings tuned A E A D G B E. The seventh string extends the pattern below a six-string layout while keeping the upper strings familiar.

Open strings and root positions

2 of the 7 open strings belong to Bb Harmonic Minor Scale: string 7 A (7) and string 5 A (7). None of those open-string tones is the Bb root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play Bb Harmonic Minor Scale on the low A string at frets 0, 1, 3, 4, 6, 8, and 9, saying each note name and degree aloud.
Build a phrase that lets A on open string 7 ring, then connect it to the nearest Bb root and two other scale tones.
Connect the Bb root positions on strings 7 through 1 at frets 1, 6, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
