C Harmonic Minor Scale in 7-String Drop A Tuning

C Harmonic Minor Scale in 7-String Drop A Tuning shows the same c 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.

Scale notes: C, D, Eb, F, G, Ab, B
Formula: 1 2 b3 4 5 b6 7
Semitones: 0 2 3 5 7 8 11
Tuning: A E A D G B E
Strings: 7
Open pitch range: A1 to E4
24-fret range: A1 to E6

Open strings and root positions

3 of the 7 open strings belong to C Harmonic Minor Scale: string 4 D (2), string 3 G (5), and string 2 B (7). None of those open-string tones is the C root, so the root must be fretted on every string.

Low-string pattern

On the lowest A string, the first-octave scale pattern falls at frets 2, 3, 5, 6, 8, 10, and 11, with the C root at fret 3. On the highest E string, the first C is at fret 8.

Practice this tuning-specific layout

Play C Harmonic Minor Scale on the low A string at frets 2, 3, 5, 6, 8, 10, and 11, saying each note name and degree aloud.
Build a phrase that lets D on open string 4 ring, then connect it to the nearest C root and two other scale tones.
Connect the C root positions on strings 7 through 1 at frets 3, 8, 3, 10, 5, 1, and 8, adding the nearest scale tone between each pair of roots.
