- How does this relate to Delta blues?
- Delta blues is one regional branch inside country blues, and the heaviest and darkest of them: open tunings, slide, droning bass figures and elastic bar counts. Country blues is the wider field, taking in Piedmont alternating-thumb picking and brighter ragtime-flavored syncopation, mostly in standard tuning and major keys, with steadier bar counts.
- How do I prompt for alternating-thumb picking?
- Split the two hands in the description: “right thumb alternates a steady two-beat bass on the low strings while index and middle fingers syncopate a melody on the trebles,” plus “standard tuning, no slide.” Asking for acoustic blues guitar usually returns slide or strumming, which belongs to a different branch.
- It keeps coming out as country music instead.
- Country blues takes its harmony and delivery from blues: flattened thirds and sevenths, AAB three-line lyrics. Country music uses major triads, narrative verse-chorus writing and often pedal steel and fiddle. Keeping “blues scale, AAB lyric form, fingerpicked acoustic guitar” in the prompt prevents the drift.
